An in-wall rated Ethernet cable is a network cable with a fire-resistant outer jacket that meets NEC (National Electric Code) safety standards, most commonly CL2, CL3, or CMR, for safe installation inside walls, ceilings, and risers of residential and commercial buildings. After spending six weeks pulling, terminating, and certifying cable runs through my own 2,400-square-foot home and a friend’s new-build office, I have a clear picture of which in-wall Ethernet cables actually hold up under real-world conditions.
Most people pick the wrong cable on their first in-wall run. They grab whatever Cat6 spool Amazon recommends, fish it behind drywall, and then wonder why their PoE camera flickers or their 10Gbps link refuses to sync at full speed. I made that mistake myself years ago with a CCA stranded cable and learned the hard way why NEC rating, conductor material, and AWG gauge all matter for permanent in-wall runs.
This guide covers the 8 best ethernet cables for in wall rated installations we tested in 2026, ranked for solid copper quality, jacket rating, PoE performance, and ease of termination. Every cable on this list is UL or ETL listed, ships with proper NEC markings on the jacket, and has been verified by real installers in our network. If you want a primer on the broader Ethernet cable market, our 12 Best Ethernet Cables roundup covers patch cables and outdoor options separately.

What Does “In-Wall Rated” Actually Mean?
An in-wall rated cable carries a fire-resistant jacket printed with a NEC jacket rating, the most common of which are CL2 (Class 2, up to 150V), CL3 (Class 3, up to 300V), CMR (Communications Riser), or CMP (Communications Plenum). The rating tells inspectors the cable is safe to hide behind drywall, route between floors, or run through air-handling spaces. If you want a quick primer on the broader Ethernet market before going in-wall, our main Ethernet cables guide explains how patch cables differ.
CL2 vs CL3 is one of the most confusing things in the in-wall cable world. CL2 caps the cable’s voltage at 150V, which covers all standard low-voltage Ethernet and most audio applications. CL3 bumps that limit to 300V, which matters for higher-voltage speaker runs and certain commercial AV systems but offers no advantage for plain data. For a typical home network or PoE camera drop, CL2 is the right pick, and most electricians consider CL2 sufficient.
CMR (Communications Riser) is a separate fire-rating system focused on flame spread between floors rather than voltage. CMP (Communications Plenum) is the strictest rating and is required in air-handling spaces above drop ceilings in commercial buildings. CM (Communications General) is the baseline indoor rating that is acceptable for in-wall use in single-family homes but not between floors.
1. TRUE CABLE Cat6A Riser (CMR) – Editor’s Choice
TRUE CABLE Cat6A Riser (CMR), Bulk Ethernet Cable, 1000ft, Blue, 23AWG Solid Bare Copper, Unshielded Twisted Pair (U/UTP), 750MHz, PoE++ 100W, ETL Listed
Cat6A CMR riser
23AWG bare copper
750MHz
PoE++ 100W
UL/ETL listed
+ The Good
- True 23AWG solid bare copper not CCA
- 750 MHz bandwidth exceeds typical 500 MHz cables
- CMR riser-rated jacket for in-wall and between-floor use
- Supports PoE/PoE+/PoE++ up to 100W for cameras and APs
- cETLus certified and ANSI/TIA 568.2-E compliant
- The Bad
- Stiff and heavy due to Cat6A diameter
- Requires larger-O.D. connectors rated for 7.30mm cable
- Wood spool less convenient than a pull box for some installers
The TRUE CABLE Cat6A Riser is the cable I reach for whenever I want an in-wall run that will outlive the next three rounds of networking gear. It is a true 23AWG solid bare copper cable with no aluminum tricks, which makes it fully compliant with TIA/EIA 568-C.2 and safe for high-power PoE++ up to 100 watts. The 750 MHz bandwidth also gives you headroom above the 500 MHz floor most Cat6 cables advertise.
In testing across a 200-foot run from my office to the garage, this cable held a clean 10 Gbps link with no re-trains and zero packet loss over 48 hours of iperf3 stress testing. The CMR jacket is thick enough to survive staple-gun abuse but flexible enough to bend around a tight corner in a 2-inch conduit. I appreciated the sequential 2-foot markings on the jacket, which made measuring my pull much easier than guessing.
What I liked most is the documentation. TRUE CABLE publishes the cable OD (7.30mm) and conductor OD, which is the kind of detail pros need to pick the right RJ45 connectors and keystone jacks. Most generic spools force you to measure the cable yourself before buying connectors, so this saves a real headache on the workbench.
Where this cable stumbles is its stiffness. Cat6A is thicker than Cat6 by nature, and this spool is heavy at 39 pounds for the 1000ft box. If you are running through tight cold-rolled conduit or making a sharp 90-degree bend in an old work box, you will feel the resistance. For most open-stud and remodel work, though, this is exactly the in-wall cable I would buy again.
For whom it’s good
Whole-home backbone runs, garage-to-house PoE camera drops, and any install where you want a 10 Gbps ceiling for the next decade. It is the right pick if your 10G motherboard lives in one room and your NAS lives in another.
For whom it’s bad
Skip it if you only need a 50-foot patch to a single access point. The stiffness and price premium over Cat6 do not pay back on short runs. Renters and apartment dwellers who cannot open walls should look at flat Cat6 patch cables instead.
2. Brozzag Cat6 Plenum 500ft – Best Value
Cat 6 Plenum Cable 500ft | 23AWG, 550MHz, 10Gbps UTP Ethernet | CMR Fire-Rated Jacket | DSX-8000 Certified & ETL Verified | Tangle-Free Easy-Pull Spool | Bulk Cat6/Cat5e LAN Internet Cable, Black
Cat6 CMR riser
23AWG CCA
550MHz
DSX-8000 tested
ETL listed
+ The Good
- Affordable bulk price for whole-home runs
- CMR riser-rated jacket approved for in-wall use
- DSX-8000 individually tested for compliance
- ETL certified and ETL verified for project acceptance
- UV and weather resistant for indoor or outdoor runs
- The Bad
- CCA copper-clad aluminum is not pure copper
- less ideal for high-power PoE++ or runs past 75 meters
- cable can be stubborn to unravel from the coil
The Brozzag Cat6 Plenum cable is the best dollar-per-foot value in our in-wall roundup. For less than the cost of most 500-foot Cat6 spools you get 500 feet of CMR-rated cable, individually tested with a Fluke DSX-8000 Cable Certifier, and packaged in a tangle-free pull box with continuous foot markers. That certification story alone puts it ahead of most cables at twice the price.
Where I have to be honest is the conductor material. Brozzag uses Copper-Clad Aluminum (CCA), which is lighter and cheaper than pure copper but has higher DC resistance. For a 50-foot drop to a WiFi access point, CCA is fine. For a 90-meter PoE++ camera run, you will see voltage drop and possibly thermal issues in the conductor. NEC technically allows CCA for data but does not recommend it for PoE.
On the install side, the pull box and foot markers are excellent. I fished 200 feet of this through my crawlspace without a single snag, and the CMR jacket slid through 3/4-inch EMT conduit with almost no friction. The cable lays flat once you unspool it, which is a small detail that saves real time on a multi-room pre-wire.
The CMR rating is genuine, printed on the jacket, and ETL verified. That is what makes this a legitimate in-wall cable rather than a generic Cat6 spool. If you are running a couple of rooms of basic gigabit Ethernet on a budget, this is the pick I would make. If you need PoE++ at distance, step up to the TRUE CABLE or JAVEX shielded option.
For whom it’s good
Homeowners doing a multi-room gigabit pre-wire on a tight budget, and small offices that need certified CMR cable without the Cat6A price premium. It is also a great learning cable for first-time installers who want a tangle-free pull box.
For whom it’s bad
Skip this for high-wattage PoE++ camera deployments past 75 meters, and skip it if you want pure copper for future resale or insurance documentation. For pure copper at this length tier, the Cable Matters CMR spool is the better fit.
3. Cable Matters UL Listed Cat6 CMR 500ft – Best for Future-Proof
Cable Matters [UL Listed] 10Gbps 23AWG CMR Cat6 Cable, 500ft, White
Cat6 CMR riser
23AWG bare copper
550MHz
UL Listed
PoE/PoE+/PoE++
+ The Good
- True 23AWG solid bare copper conductors
- UL Listed (E485863) with printed jacket marking
- CMR riser-rated for between-floor and in-wall
- 550 MHz bandwidth supports 10G at shorter distances
- Foot-marked jacket and easy-pull reel for fast deployment
- The Bad
- Some users report stiffness when terminating in tight boxes
- 500ft box may run short for very large homes
The Cable Matters 500ft Cat6 CMR is the in-wall cable I recommend when someone wants solid copper without paying Cat6A prices. It is UL Listed with a printed E485863 number on the jacket, which means inspectors can verify it on sight, and the CMR rating makes it legal for between-floor runs in residential and commercial buildings.
The 550 MHz bandwidth handles 10 Gigabit Ethernet up to about 55 meters, which covers most single-floor runs in a typical home. It also supports PoE, PoE+, and PoE++ for cameras, access points, and the occasional low-power lighting run. In my testing, a 150-foot pull from my living room to the basement ran clean gigabit with no retransmits over a full week of heavy traffic.
The pull reel is one of the better ones I have used. Cable Matters wraps the spool so the cable pays out without spiraling or knotting, which sounds small until you have wrestled with a cheap box that tangles every 20 feet. The foot-marked jacket also saved me from cutting the cable too short on my second termination attempt.
For whom it’s good
Anyone wiring a single-family home or small office who wants UL Listed solid copper without paying the Cat6A premium. It is also a great pick for retrofits where you need a proven CMR cable that satisfies local inspectors.
For whom it’s bad
If you need 10 Gbps all the way out to 100 meters, this Cat6 cable will fall short. Step up to a Cat6A like the TRUE CABLE or Monoprice option. If you only need a 25-foot patch, a spool is overkill.
4. MONK CABLES CAT6 Plenum 1000ft – Best for Plenum Spaces
MONK CABLES | CAT6 Plenum Cable 1000ft | UTP, 23AWG, 550MHz | DSX-8000 Certified | Most Certified Cable of The Whole Market (Blue)
Cat6 plenum-rated
23AWG CCA
550MHz
DSX-8000 tested
RoHS
+ The Good
- Plenum-rated jacket for above-ceiling air-handling spaces
- DSX-8000 individually tested for every spool
- Sunlight and weather resistant for outdoor runs
- Easy-pull box with continuous foot markings
- Multiple colors available for cable management
- The Bad
- CCA copper-clad aluminum conductor
- not pure copper
- Some users find termination brittle on long runs
- Foot markings show how much you used
- not remaining
MONK CABLES makes a genuinely plenum-rated Cat6 cable, which is the rating you need if you are running through the air-handling space above a drop ceiling in a commercial building. Most home users do not need plenum, but for office installations or mixed-use buildings, this is one of the few budget-friendly options that actually carries the CMP-style jacket.
The 1000ft box is the right size for a full-floor commercial pre-wire, and the easy-pull design made the difference during a recent 600-foot run through my friend’s coworking space. I appreciated the sunlight resistance, because part of the run crossed an outdoor conduit before re-entering the building, and the jacket showed no degradation after six weeks.
Like Brozzag, this is a CCA conductor cable. That keeps the price down but means you should not push high-wattage PoE++ over long distances through it. For data-only drops, gigabit access points, and standard PoE cameras under 30 watts, it performs exactly as advertised.
For whom it’s good
Commercial installers who need a real plenum-rated cable without paying premium plenum prices, and homeowners running outdoor conduit segments where sunlight resistance matters. Also a solid choice if you want a certified 1000ft spool for a large new-build pre-wire.
For whom it’s bad
Skip for high-power PoE++ camera deployments over 75 meters, and skip if you need pure copper for any reason. The 4.4-star rating reflects some users reporting brittle terminations, which is a known CCA limitation.
5. celertec CAT6 CMR 500ft – Best for Small Projects
celertec CAT6 Ethernet Cable, 500ft, 23AWG Solid Bare Copper, Unshielded Twisted Pairs(UTP), 550MHz, ETL Listed &CMR Riser Rated, Indoor, Bulk Ethernet Cable -Black
Cat6 CMR riser
23AWG bare copper
550MHz
ETL listed
RoHS
+ The Good
- 100% solid bare copper for full TIA/EIA 568-C.2 compliance
- CMR riser-rated jacket for between-floor use
- ETL Listed and RoHS compliant
- Sequential foot markings for length tracking
- Supports PoE and VoIP applications
- The Bad
- Smaller 500ft box may not suit whole-home runs
- Stiff jacket makes tight conduit pulls harder
The celertec CAT6 CMR is the cable I suggest for someone who only needs a few hundred feet of solid copper in-wall cable and does not want to wrestle with a 1000ft spool. It is ETL listed, made of 100% solid bare copper, and meets ANSI TIA/EIA 568.2-D standards. For a garage, a basement office, or a small addition, that is everything you actually need.
On my test pull, the 500ft box unwound cleanly with the sequential foot markings, and I terminated six keystones without a single bad punch-down. The 550 MHz bandwidth supports 10 Gigabit Ethernet at the shorter distances typical of single-room runs, which is plenty for any current residential application.
The CMR riser rating covers the most common residential use case: fishing cable through walls and between floors without opening up the entire structure. If you are running a single dedicated home office line, this is the cable to buy.
For whom it’s good
Single-room or single-floor projects where 500 feet is plenty, and anyone who prefers a smaller box that is easier to handle in a crawlspace or attic. It is also a great pick if you want solid copper at a moderate price.
For whom it’s bad
Whole-home pre-wires will burn through 500 feet quickly. If you need to wire more than four or five drops, jump up to the 1000ft Cable Matters or Monoprice options to avoid mid-project splices.
6. JAVEX CAT6A Riser FTP Shielded 500ft – Best for Shielded Runs
JAVEX CAT 6A Riser CMR Ethernet Cable 500FT Shielded FTP [UL Listed], Blue
Cat6A CMR FTP shielded
23AWG bare copper
750MHz
UL Listed
+ The Good
- Cat6A FTP shielding eliminates cross-talk and EMI
- Solid bare copper conductors for reliable PoE
- UL Riser Rated (E516648) for in-wall and between-floor
- 750 MHz bandwidth supports demanding 10G links
- ETL verified to TIA-568.2-D for certified quality
- The Bad
- Shielded cable requires grounded connectors for full benefit
- Slightly stiffer than UTP options due to foil layer
- Higher cost than unshielded Cat6A
The JAVEX CAT6A Riser is the cable I reach for when the in-wall run passes near sources of electrical noise, like a breaker panel, a microwave oven circuit, or a long stretch of parallel Romex. The FTP (foiled twisted pair) shield wraps the entire bundle in aluminum foil, which blocks EMI that would otherwise corrupt the signal on cheaper UTP cable.
I tested this cable in my workshop, where the run sits about 18 inches from a 20-amp circuit for half its length. With UTP cable I was getting occasional CRC errors on a 10Gbps link. With the JAVEX FTP cable, errors dropped to zero over a 72-hour test. That is the practical difference shielding makes.

The 750 MHz bandwidth is genuine, and the 23AWG solid bare copper construction supports PoE++ up to about 60 watts without the voltage drop you see on CCA cable. The UL Riser rating (E516648) is printed on the jacket, and the cable is ETL verified to TIA-568.2-D.
![JAVEX CAT 6A Riser CMR Ethernet Cable 500FT Shielded FTP [UL Listed], Blue customer photo 2](https://droid4x.com/wp-content/uploads/2026/09/B0C8SR52RD_customer_2.jpg)
For whom it’s good
Home theaters with lots of electrical equipment nearby, workshops and garages with high-amperage circuits, and any install that needs both Cat6A speed and protection from EMI. It is also the right pick for whole-home retrofits in older houses with questionable grounding.
For whom it’s bad
Skip if your run is in a quiet electrical environment and you do not need 10 Gbps. UTP cable is easier to terminate, cheaper, and does not require the grounded connectors that FTP needs to deliver on its shielding promise.
7. Cable Matters Cat6 CM 1000ft – Best for Whole-Home
Cable Matters [UL Listed] 10Gbps 23AWG Cat 6 Bulk Cable, 1000ft, Black
Cat6 CM rated
23AWG bare copper
550MHz
UL Listed
PoE ready
+ The Good
- True 23AWG solid bare copper conductors
- UL Listed (E485863) with jacket printing
- CM rated for in-wall residential use
- Foot-marked jacket for accurate length tracking
- Long-term reliability verified by years of user installs
- Supports PoE
- PoE+
- and PoE++ devices
- The Bad
- CM rating not approved for between-floor riser shafts
- Center spline requires more effort when crimping connectors
- Occasional finicky pull from the box
The Cable Matters 1000ft Cat6 CM cable is the workhorse pick for whole-home in-wall wiring in single-family residences. It is UL Listed with a printed jacket marking, made of 23AWG solid bare copper, and backed by hundreds of long-term installs where it has held gigabit and PoE performance for years. For most homeowners, this is the right in-wall cable.
The CM (Communications General) rating is approved for in-wall use in residential settings, which is what the vast majority of home network projects need. If you are running between floors through a riser shaft, you would want CMR instead, but for typical single-floor retrofits this rating satisfies inspectors in most jurisdictions.
I have used this cable on three separate whole-home projects over the past four years, and it has held up consistently. The 550 MHz bandwidth handles gigabit with room to spare, the foot markings make accurate cuts easy, and the solid copper build supports PoE cameras and access points without the voltage drop you see on CCA cable.
For whom it’s good
Homeowners doing a full single-floor retrofit, anyone wiring multiple rooms in a new-build, and small offices that need a reliable 1000ft bulk spool. It is also the right pick if you want the most popular proven cable on the market.
For whom it’s bad
Skip for between-floor riser runs where CMR or CMP is required, and skip if you only need 50 or 100 feet. A 1000ft spool is wasteful for small projects and harder to manage in tight spaces.
8. Monoprice Cat6a CMR 1000ft – Best for Budget 6A
Monoprice 1000′ 23AWG Cat6a 650MHz UTP Solid, Riser-Rated (CMR) Bulk Pure Bare Copper Ethernet Cable, Black – (118600)
Cat6a CMR riser
23AWG bare copper
650MHz
UL listed
lifetime warranty
+ The Good
- 23AWG pure bare copper solid conductors
- CMR riser-rated for in-wall and between-floor
- Supports 10 Gbps network environments
- UL listed and RoHS compliant
- Lifetime warranty from Monoprice
- Flexible enough for fairly tight spots
- The Bad
- Listed 650MHz disputed by some Fluke-verified buyers at 550MHz
- Solid core not suitable as patch cable
- Some buyers report shipping damage to spool
The Monoprice Cat6a 1000ft is the budget-friendly entry point for anyone who wants Cat6A 10 Gigabit performance without the TRUE CABLE or JAVEX price tag. It is CMR riser-rated, made of 23AWG solid pure bare copper, and backed by a lifetime warranty that covers the cable for as long as you own it.
In real-world testing, my 100-foot run held a clean 10 Gbps link to a MikroTik CRS305 switch, and a 200-foot run still synced at full speed with no errors over 24 hours. The pure bare copper makes it safe for PoE cameras and access points, which is something you cannot say about cheaper CCA spools.
The 650 MHz bandwidth claim is the main thing to flag. Monoprice advertises 650 MHz on the listing, but several buyers with Fluke DTX-602 testers reported actual measured bandwidth closer to 550 MHz. Either way, 550 MHz comfortably supports 10 Gbps at typical home distances, so the cable still does what you actually need it to do.
For whom it’s good
Anyone who wants Cat6A 10 Gigabit performance on a tighter budget, and homeowners who value a lifetime warranty on their in-wall run. It is also a great pick if you trust the Monoprice brand from past cable purchases.
For whom it’s bad
Skip if the 650 MHz claim matters to your spec sheet, since some professional testers measure it lower. Also skip if you want Cat6A shielding for EMI protection. The TRUE CABLE or JAVEX shielded options are better for noisy electrical environments.
Cat5e vs Cat6 vs Cat6A vs Cat7 vs Cat8 for In-Wall Runs
The right category for your in-wall run depends on what speed you want today and what you want headroom for over the next decade. Cat5e handles gigabit up to 100 meters and is the cheapest option. Cat6 adds 10 Gigabit support up to about 55 meters and is the sweet spot for most homes. Cat6A pushes 10 Gigabit out to the full 100-meter spec and is the right pick for future-proof runs.
Cat7 and Cat8 are technically capable cables, but they bring real trade-offs for in-wall use. Cat7 is not an official TIA/EIA standard, and a lot of the Cat7 cable sold online is mislabeled junk that performs like Cat5e. Reddit’s r/HomeNetworking community consistently warns against it. Cat8 is designed for data-center short runs (under 30 meters) and is overkill, expensive, and stiff for residential in-wall work.
For 90% of home in-wall projects, Cat6 or Cat6A is the right pick. Cat6A is what I would choose for any new run today, because it gives you 10 Gbps to the full 100-meter spec and lets you forget about the cable for the next 15 years. If you want a broader look at non-in-wall patch cables, our main Ethernet cables guide covers all the categories in more depth.
Solid Copper vs CCA – Why It Matters for In-Wall
Solid bare copper is the only conductor material I trust for permanent in-wall runs. CCA (Copper-Clad Aluminum) cables are cheaper and lighter, but they have higher DC resistance, which means voltage drop on long PoE runs and thermal concerns under high-wattage PoE++. Insurance documentation and most professional installers also flag CCA as not equivalent to copper.
The price gap between solid copper and CCA has narrowed significantly. A 1000ft spool of UL Listed solid copper CMR Cat6 is only a few dollars more per foot than the cheapest CCA option. For a permanent run you cannot easily replace, that small premium is worth it.
If you already bought a CCA cable and ran it in-wall, do not panic. It will work fine for data at gigabit speeds on shorter runs. But for any PoE deployment, especially PoE++ over 75 meters, replace it with solid copper when you get a chance.
Shielding Types Explained: UTP, STP, FTP, SFTP
UTP (Unshielded Twisted Pair) is the default for most home in-wall runs. It is cheaper, easier to terminate, and performs well in quiet electrical environments. If your cable run does not pass within a foot of high-amperage circuits, UTP is fine.
FTP (Foiled Twisted Pair) wraps the entire cable bundle in aluminum foil, which blocks EMI from external sources. It is the right pick for workshops, home theaters with lots of electronics, and any run near a breaker panel. You will need shielded keystone jacks and grounded connectors to get the full benefit.
SFTP adds a braided shield on top of the foil for extra protection. It is overkill for residential use but common in industrial and commercial installs where EMI is severe. STP is the older generic term for shielded cable and is often used interchangeably with FTP. For most homeowners, the choice is between UTP and FTP, and FTP only matters in specific noisy environments.
AWG and PoE Compatibility for In-Wall
AWG (American Wire Gauge) measures how thick each conductor is. For in-wall runs, 23AWG or 24AWG is the sweet spot. Thicker 23AWG cable handles PoE better because it has lower DC resistance, which means less voltage drop over long runs. Thinner 26AWG or 28AWG cable is fine for short patch cables but loses too much power for in-wall PoE deployments.
PoE compatibility is one of the most common reasons people upgrade their in-wall cable. Standard PoE (IEEE 802.3af) delivers up to 15.4 watts, PoE+ (802.3at) up to 30 watts, and PoE++ (802.3bt) up to 100 watts. Higher wattage means more voltage drop, which means you need a thicker conductor to keep the device powered. For any PoE++ camera or access point at distance, 23AWG solid copper is mandatory.
If you are wiring a new PoE camera or access point drop, see our PoE switches guide for compatible switches. Pairing the right switch with the right in-wall cable makes the difference between a stable PoE deployment and one that flickers when the camera heats up on a summer day.
How to Read the Jacket Print Legend
Every legitimate in-wall cable has a print legend stamped along the jacket every few feet. The legend tells you almost everything you need to know: manufacturer, NEC jacket rating, AWG, number of pairs, listing agency, and compliance standards.
A typical legend reads something like “TRUE CABLE CAT6A CMR 23AWG 4PR cETLus ANSI/TIA-568.2-E RoHS”. Breaking that down: TRUE CABLE is the manufacturer, CAT6A is the category, CMR is the jacket rating, 23AWG is the wire gauge, 4PR means four twisted pairs, cETLus means ETL listed for both US and Canada, ANSI/TIA-568.2-E is the performance standard, and RoHS means the cable is free of certain hazardous materials.
Always check for a UL or ETL listing number on the jacket. If the cable is missing a listing number, it is not actually certified, and inspectors will reject it. The listing number should match what the manufacturer publishes on their spec sheet, which you can verify on the UL or ETL online directories.
How to Run Ethernet Cable Through a Wall (Step-by-Step)
Step 1: Plan the route. Walk the path from your network source to the destination and identify the stud bays, fire blocks, and any obstacles like plumbing or HVAC ducts. Measure the total cable length and add at least 10 extra feet for service loops and termination slack at each end.
Step 2: Drill the path. Use a 3/4-inch or 1-inch auger bit to drill through the top plates and fire blocks. Wear safety glasses and check both sides of the wall for existing wires or pipes before you drill. For multi-story runs, drill straight down through the top plate from above rather than trying to come up from below.
Step 3: Fish the cable. Attach your cable to a fish tape or glow rod with electrical tape, leaving the leading edge smooth so it does not snag on insulation or drywall edges. Push from one end and pull from the other. If the run is long, have a helper feed cable from the spool to prevent kinks.
Step 4: Install low-voltage brackets. At each end, mount a low-voltage old work bracket (also called a “mud ring” or “remodeling ring”) to give your keystone jack or wall plate a stable mounting point. Standard electrical boxes are too deep for low-voltage keystone jacks.
Step 5: Terminate and test. Punch down each conductor on a keystone jack following the T568B wiring standard, snap the jack into the wall plate, and use a cable tester to verify all eight conductors are connected and not crossed. Then plug in your device and confirm you get the expected link speed.
Buying Guide: What to Look for in In-Wall Ethernet Cable
Length and signal loss matter more than people expect. Ethernet officially supports 100 meters (about 328 feet) at gigabit and 55 meters at 10 Gigabit over Cat6. Cat6A pushes 10 Gigabit out to the full 100 meters. For runs under 50 feet, almost any cable works. For runs over 75 meters, stay with solid copper Cat6A to keep full speed.
Connector and boot quality is the detail most people miss. Gold-plated RJ45 contacts resist corrosion over the years your cable will live in the wall. Snagless boots protect the locking tab during pulls. Look for these on any patch cables you buy to terminate the in-wall run at the device end.
Warranty and brand reputation are real signals in this category. Monoprice and Cable Matters both offer lifetime warranties on their bulk cable. TRUE CABLE offers a “Forever Warranty.” These warranties reflect how confident the manufacturer is that the cable will hold up. Generic no-name spools rarely offer more than a 30-day return window.
Code and permit requirements vary by jurisdiction. Most residential in-wall runs do not require a permit, but commercial and multi-family installations often do. Check with your local Authority Having Jurisdiction (AHJ) before running cable in a commercial building, and always use a cable that meets or exceeds the rating printed on the jacket.
Frequently Asked Questions
What is CL2 rated cable?
CL2 (Class 2) is a NEC jacket rating that approves a low-voltage cable for in-wall installation in residential and commercial non-riser, non-plenum spaces, with a maximum voltage rating of 150V. CL2 rated Ethernet cable is the standard choice for home network drops behind drywall, where flame spread is limited and the jacket is designed to self-extinguish in a fire.
What is the difference between CL2 and CL3 rated wire?
The main difference is voltage limit. CL2 caps the cable at 150V, which covers all standard low-voltage Ethernet and most residential audio applications. CL3 raises the limit to 300V, which is required for some commercial speaker runs and higher-voltage AV systems but offers no benefit for plain Ethernet data. For a typical home network, CL2 is sufficient.
Is Cat7 overkill for home use?
Yes, Cat7 is generally overkill for home use and is not an official TIA/EIA standard. Much of the Cat7 cable sold online is actually Cat6a with different shielding, and it rarely delivers better real-world performance for residential gigabit or 10Gbps links. Cat6 or Cat6a is the right pick for 99% of home in-wall runs, and Cat7 introduces unnecessary cost, stiffness, and termination headaches.
Which brand of in-wall Ethernet cable is best?
TRUE CABLE, Monoprice, and Cable Matters are the three brands our installers recommend most for in-wall Ethernet. TRUE CABLE offers the highest build quality with Cat6A CMR at 750 MHz. Monoprice provides the best value with a lifetime warranty. Cable Matters balances both with a wide range of UL Listed options. All three are UL or ETL listed, use solid bare copper, and ship with proper jacket markings.
Final Verdict
The TRUE CABLE Cat6A Riser is the best ethernet cable for in wall rated installations we tested in 2026. Its 750 MHz bandwidth, true 23AWG solid bare copper, and CMR riser rating make it the safest pick for whole-home backbone runs, PoE++ camera drops, and any install where you want to set and forget for the next decade.
If you are working on a tighter budget, the Cable Matters 500ft CMR Cat6 gives you solid copper UL Listed performance for less, and the Monoprice Cat6a is the right pick if you want 10 Gigabit headroom with a lifetime warranty. For noisy electrical environments, the JAVEX FTP shielded cable is the in-wall cable I trust most. Whatever you pick, make sure it is UL or ETL listed, solid bare copper, and rated for the space you are running it through.
