Middle Atlantic AV3CTCAA Poke-Thru Finish Flange with Prewired 20A Duplex

Overview

The AV3CTCAA is the aluminum finish flange and cover assembly for Middle Atlantic's AV3 poke-thru series, prewired with a 20A duplex receptacle for floor-level power access in conference rooms, training facilities, and AV-integrated workspaces. Instead of running cable trays along the floor or leaving exposed extension cords across a conference table's walking path, a poke-thru puts power exactly where the table or equipment rack sits. The AV3CTCAA covers a 4" (102mm) hole diameter and is built for floor coverings down to 1/8" minimum thickness, so it drops into standard commercial flooring builds without custom core-drilling specs.

Key Features

• 20A duplex receptacle, prewired: the unit ships with the receptacle already terminated, cutting field wiring time on install day — the electrician sets the box, lands the feed, and the flange assembly is ready to close out.
• Standard or isolated ground wiring: lets an integrator spec isolated ground where sensitive AV or data equipment needs clean power separate from building ground, without swapping the whole poke-thru unit.
• 4" (102mm) hole diameter: matches the standard AV3 poke-thru core-drill spec, so this is a drop-in flange for an existing or newly cut AV3-family opening rather than a custom fit.
• 1/8" minimum floor covering thickness: confirms the flange closes flush on typical carpet tile, LVT, or thin hard-surface finishes — check finished floor buildup against this minimum before ordering if the space has thick padding or raised flooring.
• Adapter compatible — Legrand AVIP, Extron MAAP, Wiremold Open System, Ortronics TracJack Series II: the flange accepts modular AV/data adapter plates from these lines, so one poke-thru opening can mix power with HDMI, USB-C, or RJ45 pass-through without re-coring the floor for a second box.
• Five finish colors — Gray, Black, Ivory, Brushed Aluminum, Brass: lets the flange match table finishes or flooring in a boardroom instead of standing out as a visible utility component.
• Aluminum flange construction: holds up to foot traffic and rolling equipment carts in a floor-mounted location better than a plastic cover plate.
• 1.00 lb shipping weight: a compact, low-profile component — freight and handling stay minimal for integrators ordering multiples across a multi-room buildout.

Integration & Compatibility

The AV3CTCAA is part of the Middle Atlantic Middle Atlantic catalog of poke-thru and floor-access hardware, and it's built to pair with the broader AV3 poke-thru body and fire-rated housing rather than stand alone — confirm the matching AV3 floor box body is already specified or in place before ordering the flange separately. Because the adapter bay accepts Legrand AVIP, Extron MAAP, Wiremold Open System, and Ortronics TracJack Series II modules, it's a practical fit for rooms already standardized on one of those adapter ecosystems for data and AV pass-through. For rooms built around a broader AV over IP deployment, landing power and signal at the same floor point simplifies cable runs to table-mounted control panels or camera hubs. If you're planning power drops across a multi-room facility, a PoE and power planning guide is worth reviewing alongside standard AC poke-thru placement to decide where powered AV endpoints belong versus where a simple 20A duplex like this one covers the need. For rooms also running cameras and streaming equipment at the table, coordinate floor power placement with camera and mic power runs early — retrofitting a second poke-thru after flooring is finished is disruptive and costly.

What's in the Box

The AV3CTCAA ships as the finish flange and cover assembly with the 20A duplex receptacle prewired. Confirm with the quote or order confirmation whether the matching AV3 floor box body ships separately, since the flange is sold as the finish/cover component of the AV3 poke-thru system.

Frequently Asked Questions

Q: What's the warranty on the AV3CTCAA?

A: The AV3CTCAA carries a 2-year manufacturer warranty.

Q: Is the AV3CTCAA TAA compliant?

A: Yes, the AV3CTCAA is TAA compliant.

Q: What size hole does the AV3CTCAA require?

A: The AV3CTCAA fits a 4" (102mm) diameter hole, matching the standard AV3 poke-thru core-drill spec.

Q: What floor covering thickness does the AV3CTCAA support?

A: A minimum of 1/8" floor covering thickness is required for proper flange fit.

Q: Can the AV3CTCAA take isolated ground wiring?

A: Yes, the receptacle wiring supports either standard or isolated ground configurations.

Q: What adapter systems work with the AV3CTCAA?

A: It's adapter compatible with Legrand AVIP, Extron MAAP, Wiremold Open System, and Ortronics TracJack Series II modules.

Karl Wilson

I spec poke-thru boxes on a lot of conference room retrofits, and the detail that decides whether the AV3CTCAA fits is the 4" (102mm) hole diameter — that's the standard AV3-family core-drill, so if you've already got an AV3 opening cut, this flange drops right in rather than forcing a second core-drill pass.

Technical Highlights:

• 20A duplex, prewired: the receptacle is terminated at the factory, which saves real field labor versus wiring a duplex from scratch inside a floor box on install day.
• Standard or isolated ground: gives you the option to isolate ground for sensitive AV or data gear sharing the same poke-thru without needing a different SKU.
• 1/8" minimum floor covering: that's the threshold to check against your finished floor buildup — thin carpet tile or LVT clears it easily, but confirm before assuming it works with thicker padded carpet or raised access flooring.

Deployment Considerations:

• This is the flange/cover assembly, not the full poke-thru body — make sure the matching AV3 floor box housing is already in the floor or specified alongside the AV3CTCAA before ordering.
• The adapter bay works with Legrand AVIP, Extron MAAP, Wiremold Open System, and Ortronics TracJack Series II — if your job is standardized on a different adapter platform, confirm compatibility before you core-drill.

This is the right call for a boardroom or training room retrofit where the AV3 core-drill is already in place and you need a clean, finish-matched 20A power point at the table without a second floor penetration for data — pick a finish color (Gray, Black, Ivory, Brushed Aluminum, or Brass) that matches the table or flooring and pair it with one of the supported adapter plates if the room also needs HDMI or RJ45 at the same location.
