A wall-mounted TV with a nest of cables dangling below is the single most common eyesore in modern living rooms. An AV Wall Box solves this by creating a recessed cavity inside the drywall that hides power cords, HDMI cables, and streaming sticks completely, letting your TV sit flush against the wall without any visible wiring.

I’m Min — the co-founder and writer behind Gadgets Feed. I have spent hundreds of hours analyzing product specifications, customer feedback data, and installation requirements to separate the wall boxes that deliver a clean, safe, and professional result from those that create new headaches.

After evaluating internal volume capacity, included accessories, material fire ratings, and retrofit compatibility across dozens of models, I settled on the seven top contenders that define the best av wall box options available today for any install scenario.

How To Choose The Best AV Wall Box

Selecting the right AV Wall Box comes down to three variables: the depth of your wall cavity, the number of devices you need to hide, and whether you want integrated power or just low-voltage pass-through. A box that is too shallow won’t accommodate a power brick, while one that is too narrow forces HDMI plugs into sharp bends that degrade signal.

Internal Depth and Device Clearance

The single most critical measurement is the internal depth of the enclosure. Many AV Wall Boxes claim a 3.5-inch depth, but the actual usable space is reduced by the thickness of the faceplate and the outlet receptacles. If you plan to hide a Fire Stick, Apple TV, or Roku inside the box, look for a minimum internal cavity of 3.0 inches after installation — anything less forces the device to protrude past the wall surface.

Power Certification and Code Compliance

Never place a standard extension cord inside a wall — it is a fire hazard and violates electrical code. The right AV Wall Box includes a UL or ETL certified power assembly with a 9-foot cord that plugs into a nearby outlet. This assembly uses in-wall rated wiring and tamper-resistant receptacles. Low-voltage cables (HDMI, Ethernet, coax) can share the same cavity only when separated by a divider or when the power section is a dedicated sub-compartment.

Best Overall

1. ECHOGEAR 9″ In-Wall TV Media Box

3.9″ DepthUL Certified Power

The ECHOGEAR 9″ delivers the deepest usable cavity in this roundup at 3.9 inches, which is enough to swallow a Samsung One Connect Mini, Apple TV, or Fire TV Stick alongside a power strip. The enclosure measures 14.3 inches wide, fitting snugly between 16-inch on-center studs without needing to cut framing. WiFi-transparent materials ensure streaming signal isn’t degraded — a real concern with metal enclosures.

The included trim ring provides a clean 10.84″H x 15.87″L finished look on the wall surface, and the entire kit is UL certified for safe in-wall power routing. Installation is DIY-friendly in about 15 minutes with the included hardware and step-by-step guide. The box surface is paintable to match any wall color seamlessly.

Customer feedback consistently highlights how the One Connect box fits perfectly with the trim ring, though some users note that the knockouts required snips rather than snapping out cleanly. The depth also accommodates duplex outlets easily, making it a rare true 2-in-1 solution for device storage and cable concealment.

Why it’s great

  • Deepest cavity (3.9″) fits most streaming boxes flush
  • UL certified power assembly for code-compliant install
  • WiFi-transparent materials prevent signal interference

Good to know

  • Knockouts require snips instead of snapping out
  • Premium price point compared to basic kits
Professional Grade

2. Arlington TVBU810-1 TV Box with Flange

UL & CSA ListedMade in USA

The Arlington TVBU810-1 is a staple in professional home theater installations, trusted by electricians for its rugged paintable plastic construction and dual certification (UL and CSA). The interior measures 10.65″ x 12.53″ with a 3.14″ depth, providing generous room for duplex outlets, power bricks, and low-voltage cabling. The included 1.5-inch knockout accepts ENT conduit for structured wiring.

This box ships with cover blanks, a wall plate, cable entry devices, and connectors for unused openings — everything needed for a finished install. The flanged design creates a 1.13-inch border around the cutout that hides rough drywall edges. Users frequently note that it holds a duplex surge-protected outlet plus TV, soundbar, and streaming stick connections without cramping.

The main tradeoff is that the flange extends about 1/4 inch past the wall surface, which can interfere with TV brackets that mount directly over the box. Several users solved this with 1.5-inch fender washers to space the bracket out slightly. The box lacks an integrated power cord, so you must install your own receptacles and wiring.

Why it’s great

  • Dual UL and CSA listing for professional installs
  • Multiple knockouts and included blank plates
  • Ample 12.53″ width for large equipment

Good to know

  • Flange protrudes 1/4″ from wall surface
  • Does not include pre-wired power assembly

3. Mount-It! In-Wall TV Cable Concealer Kit

Triple OutletETL Certified

The Mount-It! kit stands out by including a quality drywall saw, accurate cutting templates, and a 9-foot ETL certified power cord with three duplex outlets — enough to power a TV, soundbar, and game console simultaneously. The large faceplate measures 6.3″ x 7.9″ and covers the cutout cleanly, while the recessed opening accommodates multiple HDMI and Ethernet connectors without strain.

The plug-in design requires no hardwiring, making it ideal for renters or homeowners who want a clean install without calling an electrician. The minimum wall cavity depth requirement is just 2.4 inches, which fits standard 2×4 wall construction easily. The included instructions are clear, and customers frequently complete the job in under 30 minutes.

The triple outlet configuration is a genuine advantage for busy entertainment centers, but the overall enclosure depth is shallower than the ECHOGEAR or Arlington options, meaning it cannot fully conceal a streaming box like an Apple TV or Roku Ultra inside the wall. The power cord is pre-attached, so placement must account for reaching a nearby wall outlet.

Why it’s great

  • Three tamper-resistant outlets in a single kit
  • Includes high-quality drywall saw and templates
  • Low 2.4″ minimum cavity requirement

Good to know

  • Shallow cavity cannot hide streaming devices
  • Pre-attached cord limits placement flexibility

4. Celendor Cable Concealer Kit (B0F84K14GG)

Brush Plate5 Year Warranty

Celendor’s kit pairs a recessed outlet box with a dedicated brush wall plate for low-voltage cables, creating a clean two-plate system that separates power from signal wires. The brush plate measures 4.53″ x 4.49″ and fits over 100 thin cables without damaging jacketings. The included 9.8-foot power cord is flame-retardant polycarbonate rated for in-wall use.

Installation is straightforward with die-cut cardstock templates that customers praise for accuracy — much better than paper that tears during tracing. The kit requires a minimum wall cavity depth of 3.74 inches to accommodate the recessed power box. The large bottom opening fits multiple HDMI plugs side by side, which is a common pain point with smaller brush plates.

The 5-year warranty is the longest of any kit in this roundup, reflecting confidence in the flame-retardant PC material. However, the power section is a single duplex outlet rather than a triple, so users with many devices may need an additional power strip inside the cavity, which reduces available space for cable routing.

Why it’s great

  • Dedicated brush plate for tidy low-voltage organization
  • 5-year warranty for long-term peace of mind
  • Flame-retardant polycarbonate construction

Good to know

  • Only one duplex outlet included
  • Requires 3.74″ minimum wall cavity depth
Ultra-Flat Plug

5. Celendor Cable Management Kit (B0FSKD4SVN)

0.28″ Flat PlugETL Certified

This Celendor kit solves one of the most irritating problems with recessed outlets: the power plug itself sticking out too far. The unique 45-degree flat plug measures just 0.28 inches thick, sitting completely flush against the wall so the TV can mount without a gap. The 9.8-foot ETL certified power cord delivers 125V/15A output (1875W max) through two tamper-resistant outlets with safety shutters.

The kit includes a drywall saw and accurate cutting templates, so no additional tools are needed. Customers consistently rate it 5 stars for ease of installation and the professional finish it provides. The fire-resistant materials and tamper-resistant (TR) outlets make this a strong choice for families with children and pets.

The main limitation is the same 3.74-inch minimum cavity depth requirement, and the single brush plate is sized for the outlet box only — there is no separate low-voltage pass-through plate, so HDMI and Ethernet cables must share space with the power cord inside the cavity. The warranty is a standard 2 years, shorter than the other Celendor kit.

Why it’s great

  • 0.28″ flat plug enables truly flush TV mounting
  • ETL certified with tamper-resistant safety shutters
  • Includes drywall saw and accurate templates

Good to know

  • No separate low-voltage brush plate included
  • 2-year warranty shorter than sibling model
Large Cavity

6. Dremica In-Wall TV Box with Flange

11.9″ x 8.4″2 Outlets

The Dremica box offers one of the largest usable cavities in this roundup at 11.9″ x 8.4″ x 3.14″ deep, making it ideal for home theater systems that connect multiple devices like sound systems, satellite TV, and DVR boxes. The kit includes two 15A 125V duplex receptacles, four NM94 cable connectors, two brush openings, and a blank cover plate for flexible configuration.

Installation supports both horizontal and vertical orientations using integrated mounting wing screws that clamp the box flush against drywall. The paintable plastic flange measures 13″ x 9.5″ with a 1.13-inch border to cover rough cutout edges. The kit also includes a cutting template and a 2-year warranty.

Customer feedback is positive overall, but several users note that the included cardboard template is not cut to the correct dotted line — you must cut on the line itself for the hole to match. Also, the duplex outlets are spaced closely, so bulky wall warts may block the second receptacle. The internal depth is adequate for most cables but too shallow for larger streaming devices.

Why it’s great

  • Very large 11.9″ x 8.4″ cavity for multi-device setups
  • Horizontal and vertical installation flexibility
  • Includes two duplex receptacles and brush openings

Good to know

  • Cardboard template may require cutting on the line
  • Outlets close together may block large power adapters

7. Leviton 14″ SMC Structured Media Enclosure with Cover

Alloy Steel14″ Size

The Leviton 14″ SMC is not a standard AV Wall Box — it is a structured media enclosure designed to house network gear like a modem, router, patch panel, and up to 12 Ethernet runs. At 15.32″H x 15.62″W x 3.68″D, it fits between 16-inch studs and provides ample space for organized low-voltage infrastructure. The alloy steel construction with powder-coated finish resists corrosion in wall cavities.

Multiple knockouts on top and bottom include two 2-inch knockouts for conduit entry. The base has a cutout for mounting single and double gang junction boxes. Positive tabs on the sidewalls prevent the enclosure from falling through the studs during installation. The flush-mount cover provides a clean finished appearance.

This enclosure is the best choice if your primary goal is hiding a router and cable modem rather than TV cables. However, it lacks pre-installed power receptacles or a power cord — you must add your own electrical box inside the enclosure or use an external outlet. Some users report sharp edges on the steel cutouts, so handling with gloves is advisable.

Why it’s great

  • Large steel enclosure fits full router + modem + patch panel
  • Positive tabs prevent falling through studs during install
  • Multiple 2-inch knockouts for conduit runs

Good to know

  • No integrated power – requires separate electrical install
  • Steel edges may be sharp – gloves recommended

FAQ

Can an AV Wall Box fit between standard 16-inch on-center studs?
Yes, most AV Wall Boxes are designed to fit between 16-inch on-center stud spacing. The outer dimensions of the box (including flanges) typically range from 13 to 16 inches wide, while the rough-in opening is smaller. Always measure the rough opening width against your actual stud spacing — some historic homes use 24-inch centers or have non-standard framing that requires a narrower box like the ECHOGEAR 9″ at 14.3 inches.
Is it safe to run power cables and HDMI cables in the same wall box?
Yes, but only when the power assembly is UL or ETL certified for in-wall use and the low-voltage cables are separated from line-voltage wiring. Many AV Wall Boxes use a built-in power cord assembly with a dedicated compartment or divider that keeps 120V wiring away from HDMI and Ethernet cables. If the box does not have a physical divider, the power and low-voltage cables must enter through separate knockouts and should not be bundled tightly together to avoid inductive interference.
Can an AV Wall Box be installed in an exterior wall with insulation?
Installation in an exterior wall is possible but requires extra steps for proper insulation and vapor barrier management. You must cut the insulation cleanly around the box cavity and seal any gaps with fire-stop caulk or spray foam to prevent air infiltration. Some boxes include a foam gasket or a vapor barrier flange. Condensation from temperature differentials is a risk — a metal box like the Leviton enclosure can conduct cold, while plastic boxes are generally better insulated. For exterior walls, a plastic box with a sealed back is preferred.

Final Thoughts: The Verdict

For most users, the best av wall box winner is the ECHOGEAR 9″ In-Wall TV Media Box because it combines the deepest usable cavity (3.9″) with UL certified power, WiFi-transparent materials, and a trim ring that creates a truly flush finish — all while fitting Samsung One Connect boxes and streaming sticks without protrusion. If you need a professional-grade box with dual UL/CSA certification and the flexibility to wire your own receptacles, grab the Arlington TVBU810-1. And for a budget-friendly network hub that hides a full router and patch panel behind a clean steel door, nothing beats the Leviton 14″ SMC Structured Media Enclosure.
