Middle Atlantic 6AT2PBZ Prewired Flush-Cover Poke-Through Floor Device

Overview

The Middle Atlantic 6AT2PBZ is a prewired, flush-cover poke-through floor device from the Evolution 6AT2 series, designed for commercial conference rooms, boardrooms, and open-plan collaboration spaces where surface cable trays aren't an option. It ships ready to install in a bronze finish, with an 11.5" x 11.5" x 19.5" (292.1 x 292.1 x 495.3 mm) overall assembly that drops into a cored concrete or raised-access floor to deliver power and AV connectivity cleanly to a tabletop or workstation. If you're specifying Middle Atlantic infrastructure for a corporate AV buildout, the 6AT2PBZ is the prewired, drop-in option that eliminates field wiring labor at the floor unit itself.

Key Features

• Flush Cover Style: The flush-mount lid sits level with the surrounding floor surface when closed, eliminating trip hazards in high-traffic conference environments. Unlike pop-up or raised-cover variants, flush lids are the standard specification for formal boardroom settings where aesthetics and safety codes intersect — a frequent requirement in commercial poke-through floor devices.
• Prewired from the Factory: Arriving prewired means the internal wiring harness is installed and tested before the unit leaves the factory. On a multi-room project, that translates directly to fewer field labor hours per drop — the electrician installs the assembly and terminates to the building's circuits rather than wiring the device interior from scratch. Factor this into your labor estimate when comparing to field-wired alternatives.
• Bronze Finish (Color: Bronze): The 6AT2PBZ's bronze finish coordinates with brushed-metal or dark-wood conference table surfaces without requiring a custom insert kit. Specifying finish at order time avoids the common last-minute swap when a silver or black unit doesn't match the furniture package.
• TAA Compliant: This unit meets Trade Agreements Act requirements, making it eligible for federal government, GSA schedule, and other public-sector procurement vehicles where TAA compliance is mandatory. If your project involves a government agency or federally funded facility, this is the spec to confirm — non-TAA units are disqualifying regardless of technical fit.
• Compact Body Dimensions (7.75" W x 7.25" H x 16.25" D): The 16.25" installation depth (41.3 cm) determines the minimum floor/plenum clearance required below the finished surface. Confirm your slab-to-subfloor or plenum depth before ordering — a 16.25" barrel needs that clearance, and retrofitting a core that's too shallow requires a more expensive low-profile variant. Width at 7.75" and height at 7.25" define the in-floor footprint the electrician cuts.
• Overall Assembly Footprint (11.5" x 11.5"): The 11.5" square top plate covers the cored opening and provides the finished surface surround. This footprint is large enough to accommodate multiple service inserts (power, data, AV) in a single floor location — reducing the number of separate floor penetrations on densely serviced conference tables.

Integration & Compatibility

The 6AT2PBZ is part of Middle Atlantic's Evolution 6AT2 poke-through series, designed to accept standard insert modules for power (15A/20A duplex), data (keystone or modular), and AV connectivity. The prewired harness connects to your building's electrical feed at the junction box below the floor. For full insert and cover plate compatibility, cross-reference the 6AT2 series accessory matrix from Middle Atlantic — insert modules and service covers are ordered separately based on your connectivity mix. When planning cable management for a conference room, route low-voltage data and AV cabling through dedicated compartments in the device rather than sharing conduit runs with line voltage to stay compliant with NEC separation requirements.

TAA compliance makes this unit directly compatible with procurement on GSA schedules and federal construction contracts. Pair with a Middle Atlantic power strip or raceway at the equipment rack to complete the end-to-end power path from floor device to rack-mounted gear.

Frequently Asked Questions

Q: Is the Middle Atlantic 6AT2PBZ TAA compliant?

A: Yes. The 6AT2PBZ is TAA compliant, making it eligible for federal government and GSA schedule procurement where Trade Agreements Act compliance is required.

Q: What is the installation depth required for the 6AT2PBZ?

A: The 6AT2PBZ requires a minimum floor or plenum clearance of 16.25 inches (41.3 cm) below the finished floor surface to accommodate the device barrel. Verify your slab-to-subfloor or raised-floor clearance before ordering.

Q: Does the 6AT2PBZ come prewired?

A: Yes. The unit ships factory-prewired, reducing field wiring labor at the floor device. The electrician connects the prewired harness to the building's circuit feed below the floor.

Q: What finish is the 6AT2PBZ available in?

A: The 6AT2PBZ ships in a bronze finish. If your project requires a different finish (silver, black, etc.), check the Middle Atlantic 6AT2 series for alternate color SKUs.

Q: What is the overall footprint of the 6AT2PBZ floor plate?

A: The overall assembly dimensions are 11.5" x 11.5" x 19.5" (292.1 x 292.1 x 495.3 mm). The 11.5" square top plate covers the cored floor opening; the 19.5" total length includes the barrel depth below the floor surface.

Q: Is the 6AT2PBZ a flush-cover or pop-up cover device?

A: Flush cover. When closed, the lid sits level with the surrounding floor, which is the standard specification for boardrooms and formal conference spaces where raised covers create trip hazards or fail finish standards.

The spec that matters most on the 6AT2PBZ before you commit to an order is the 16.25-inch barrel depth — I've seen more than a few retrofits stall because the installer cored the slab only to find 12 inches of plenum clearance. Measure the void first. Once you've confirmed the depth works, the rest of the 6AT2PBZ install is straightforward: prewired from the factory, bronze flush cover, TAA-compliant for public-sector jobs.

Technical Highlights:

• 16.25" Installation Depth: Sets the hard minimum plenum or subfloor clearance required — non-negotiable before coring. Mismatch here means a costly field correction or a different SKU.
• 11.5" x 11.5" Top Plate: Covers the cored opening cleanly and provides enough real estate for multi-service insert modules (power + data + AV) in a single floor penetration, cutting the number of separate cores on a dense conference table layout.
• TAA Compliant: Qualifies for federal and GSA procurement without a separate compliance review — a time-saver on government or publicly funded facility projects.

Deployment Considerations:

• The prewired harness terminates to the building circuit below the floor — confirm your local electrician is familiar with Middle Atlantic's termination spec for the 6AT2 series before scheduling the rough-in.
• Bronze is a single finish option on this SKU; if the furniture package specifies brushed nickel or matte black, order the correct finish variant from the 6AT2 series at the start of the project — swapping a flush floor device after concrete work is finished is an expensive change order.

Best deployment fit: corporate boardrooms and formal conference suites in new construction or gut-renovation projects where the floor void is confirmed at 16.25" or deeper, the finish spec is bronze, and the project falls under a federal or GSA procurement vehicle requiring TAA compliance.
