Middle Atlantic 6AT2BK 6-Inch Recessed Poke-Through Floor Box with Flush Cover
Overview
The Middle Atlantic 6AT2BK is a recessed, unwired poke-through floor device from the Evolution 6AT2 Series, designed to deliver flush-finished cable access points in commercial flooring. At 11.5" x 11.5" x 19.5" overall (292.1 x 292.1 x 495.3 mm), it fits standard commercial slab cuts and sits at floor level with a clean flush cover — no raised lip to catch foot traffic or create trip hazards in open-plan offices, conference rooms, or AV-integrated spaces. The 6AT2BK ships in black and is TAA compliant, making it eligible for U.S. federal and GSA procurement projects without additional vetting.
The unit is unwired (prewired: no), meaning you provision it with the connectivity modules your specific project requires — power, data, AV, USB, or any combination the 6AT2 bracket system supports. This approach avoids paying for wired configurations you won't use and lets you standardize on a single floor box SKU across a job site while varying the insert mix by zone.
For Middle Atlantic infrastructure products and the broader AV and structured cabling infrastructure line, the 6AT2BK is the base chassis that anchors a modular floor connectivity system. Pair it with the appropriate cable management accessories and insert modules for a complete installation.
Key Features
- Flush Cover Style: the cover sits level with the finished floor surface — no raised bezel to snag wheeled furniture or create ADA-relevant tripping edges. Critical in high-traffic conference and collaboration spaces where aesthetics and safety both matter.
- Unwired Configuration: ships without pre-installed power or data modules, so you select only the inserts your project needs. Avoids waste on large multi-zone deployments where power density or data port counts differ room to room.
- TAA Compliant: meets Trade Agreements Act requirements, qualifying the 6AT2BK for U.S. government, federal agency, and GSA schedule projects without a waiver process — a hard requirement on many public-sector bids.
- Black Finish: coordinates with dark carpet tile, polished concrete, and most commercial flooring in corporate and government interiors without requiring custom finishing.
- Overall Dimensions 11.5" x 11.5" x 19.5": the 19.5" depth (495.3 mm) means you need confirmed slab-to-subfloor clearance before ordering — measure your concrete deck depth; this unit requires a meaningful below-grade cavity.
- Compact Footprint 7.75" W x 7.25" H (body): the body dimensions (7.75" x 7.25" x 16.25") describe the device envelope inside the floor cut — useful when coordinating with structural or flooring contractors on core dimensions.
Integration & Compatibility
The 6AT2BK is the base chassis of the Middle Atlantic Evolution 6AT2 Series. As an unwired unit, it accepts Middle Atlantic's modular insert system — power, duplex data, HDMI, USB-A/C, and other AV connectivity modules mount into the bracket assembly. Verify insert compatibility against the 6AT2 Series insert catalog before specifying; not all third-party inserts are dimensionally compatible. This unit is suited for open-plan offices, boardrooms, training facilities, and any commercial space where floor-level connectivity is preferable to wall or column routing. For structured cabling projects requiring surface or wall-mount alternatives, compare against above-floor raceway or wall-box options in the same line before committing to a slab cut.
Frequently Asked Questions
Q: Is the Middle Atlantic 6AT2BK TAA compliant?
A: Yes. The 6AT2BK is TAA compliant, making it eligible for U.S. federal and GSA procurement projects.
Q: Does the 6AT2BK come pre-wired with power or data modules?
A: No. The 6AT2BK ships unwired — it is the base chassis only. You select and install the specific Middle Atlantic 6AT2 Series insert modules (power, data, AV, etc.) required for your application.
Q: What are the overall installed dimensions of the 6AT2BK?
A: The overall dimensions are 11.5" x 11.5" x 19.5" (292.1 x 292.1 x 495.3 mm). The device body is 7.75" wide x 7.25" high x 16.25" deep. Plan for adequate below-slab clearance before specifying.
Q: What color is the 6AT2BK cover?
A: The 6AT2BK is finished in black, coordinating with dark commercial flooring and standard corporate interiors.
Q: What cover style does the 6AT2BK use?
A: It uses a flush cover style, meaning the cover sits level with the finished floor surface — no raised lip or bezel above floor grade.
The spec I always flag on the 6AT2BK before a project goes to contract is the 19.5-inch installed depth. That 495mm below-slab requirement catches integrators off-guard on retrofit jobs — a 4-inch concrete deck with a shallow plenum simply won't accommodate this unit, and you find out after the floor is cut. Confirm cavity depth with your structural or GC contact before the 6AT2BK goes on the BOM.
Technical Highlights:
- Flush Cover (no raised bezel): level with finished floor grade — relevant for ADA compliance reviews and for spaces with rolling chairs or wheeled AV carts where a raised lip creates real liability exposure.
- TAA Compliant: meets Trade Agreements Act requirements — a binary pass/fail on federal and GSA bids; the 6AT2BK passes without a waiver, which matters when procurement timelines are tight.
- Unwired chassis (Prewired: No): at 7.75" x 7.25" x 16.25" body dimensions, the insert bay is open — configure it once per the zone's connectivity spec rather than paying for a pre-wired variant that may not match your data/power ratio.
Deployment Considerations:
- The 19.5" overall depth (495.3 mm) is the critical install constraint — measure actual slab-to-structural floor clearance, not just nominal plenum height, before committing to a floor core location.
- This unit ships without inserts; source Middle Atlantic 6AT2 Series modules separately and verify dimensional fit before the installation crew is on site — a mismatched insert on a sealed floor cut adds real rework cost.
The 6AT2BK is the right call for new-construction or major-renovation corporate interiors and government facilities where TAA compliance is a contract requirement and a clean flush-floor aesthetic is non-negotiable — particularly boardrooms, federal training facilities, and open-plan offices where floor boxes see daily foot and furniture traffic.
