Wiremold Middle Atlantic AV3ATCBK Assembled Floor Poke-Through Device

Overview

The Middle Atlantic AV3ATCBK is an assembled, surface-style floor poke-through device engineered for AV infrastructure installations where cable management needs to emerge cleanly from the floor — conference rooms, boardrooms, training spaces, and open-plan collaboration areas where surface-mounted conduit is not acceptable. The AV3ATCBK ships as a complete assembly in a matte black finish, reducing field labor compared to sourcing and assembling individual components separately.

TAA compliance is confirmed for this SKU, making it a straightforward specification for U.S. federal facilities, GSA-schedule projects, and any deployment with TAA sourcing requirements. If your project has a Buy American Act or TAA checkbox, the AV3ATCBK clears it without exception requests.

Key Features

• Assembled Configuration: Ships ready to install as a complete poke-through assembly — no separate trim ring, insert, or collar sourcing required. Reduces installation time and minimizes the risk of mismatched components on site.
• 20A Circuit Rating: Rated for 20-ampere service, which accommodates standard commercial AV power loads — projectors, displays, AV receivers, and charging infrastructure — without requiring a dedicated 20A circuit upgrade on most commercial builds.
• Surface-Style Form Factor: Designed for surface-mount floor applications where a flush poke-through must transition cables from below the floor to above cleanly. Appropriate for raised-floor environments and slab applications with proper core drilling.
• Black Finish (BK): The matte black color integrates visually with dark conference table surfaces and floor finishes — avoids the institutional gray appearance of generic electrical floor boxes in client-facing spaces.
• Trim Cover Included (TC): The trim cover is part of the assembly, providing a finished, professional appearance when ports are not in active use and protecting the opening from debris ingress.
• TAA Compliant: Verified TAA compliance on this SKU supports procurement through GSA schedules and federal/state contracts without sourcing exception paperwork.
• Compact Footprint: At 8.25 in × 8.25 in (21 cm × 21 cm) with a 17 in (43.2 cm) depth, the AV3ATCBK fits standard commercial floor box cutouts while providing enough depth to manage cabling below the floor plane without tight-radius bends that can damage cable shielding.

Integration and Compatibility

The AV3ATCBK is part of Middle Atlantic's Middle Atlantic AV infrastructure line, designed to pair with compatible inserts, power modules, and cable pass-through components from the same family. When specifying for a conference room buildout, verify that your chosen inserts — HDMI, USB-C, power, or data — are compatible with the AV3ATC series mounting footprint before ordering. Pair with appropriate AV mounting and cable management accessories to complete a fully managed signal path from the floor box to the display.

For larger deployments requiring multiple floor positions, consult your floor plan against the 8.25 in × 8.25 in cutout dimensions early in the design phase — table bases, chair rails, and subfloor structural members can constrain placement options in retrofit scenarios.

Frequently Asked Questions

Q: Is the AV3ATCBK TAA compliant?

A: Yes. TAA compliance is verified for the AV3ATCBK SKU, making it suitable for U.S. federal, state, and GSA-schedule procurement without exception requests.

Q: What are the dimensions of the AV3ATCBK?

A: The AV3ATCBK measures 8.25 in wide × 8.25 in tall × 17 in deep (21 cm × 21 cm × 43.2 cm). Plan your floor cutout and below-floor depth accordingly before ordering.

Q: What amperage is the AV3ATCBK rated for?

A: The AV3ATCBK is rated for 20A service, suitable for standard commercial AV power loads in conference and collaboration spaces.

Q: Does the AV3ATCBK include a trim cover?

A: Yes. The TC designation in the product name confirms a trim cover is included as part of the assembly.

Q: What color is the AV3ATCBK?

A: Black (BK). The matte black finish is suited to conference table and dark floor surface installations.

The AV3ATCBK is a detail that integrators overlook until it's too late in a project — the 17-inch depth (43.2 cm) is the spec that actually drives compatibility with the floor construction, not the surface footprint. On slab pours or shallow raised-floor systems, 17 inches of required depth can conflict with structural or mechanical elements below; confirm with the GC before the floor box cutout is made, not after.

Technical Highlights:

• 20A Rating: Handles the combined load of conference room AV gear — a 4K display, an HDMI switcher, and a laptop charging brick — without pulling a new dedicated circuit on most commercial electrical panels.
• 8.25 × 8.25 in Footprint: Standard enough to fit pre-cut conference table grommets and floor box cutouts on most commercial furniture systems, but measure before ordering — non-standard table bases vary.
• TAA Compliance: Confirmed on this SKU — eliminates the sourcing exception paperwork on GSA and federal education contracts where TAA is a hard requirement, not a preference.

Deployment Considerations:

• The 17 in depth requires clear vertical space below the floor surface — in raised-floor data center or modular floor systems, verify clearance against cable tray and power bus locations before cutting.
• The AV3ATCBK ships as an assembled unit (ASY in the model name) with trim cover included; confirm that your specific insert modules (HDMI, USB-C, power) are compatible with the AV3ATC series before finalizing the bill of materials.

Best fit for a corporate conference room or higher-education collaboration space renovation where TAA sourcing is required and the design calls for a clean black floor-box finish that won't look out of place around a dark executive table.
