Middle Atlantic 6AT2GY Recessed Poke-Through Floor Box with Flush Cover

Overview

The Middle Atlantic 6AT2GY is a recessed, un-prewired poke-through floor device from the Evolution 6AT2 series, designed to deliver clean cable access points through concrete or raised-access flooring in commercial environments. Where surface-mount raceways or exposed conduit runs are unacceptable — boardrooms, executive offices, open-plan trading floors, and AV-integrated conference spaces — the 6AT2GY sinks flush with the finished floor surface and disappears when closed. The flush gray cover keeps the footprint unobtrusive and the floor plan clean.

This unit ships un-prewired, giving the integrator full control over which modules, outlets, and data inserts populate the device — an important distinction from prewired variants when the exact port mix is project-specific or subject to change during construction.

Key Features

• Flush Cover Style: The flush cover sits level with the finished floor surface, eliminating the tripping hazard and visual interruption of raised-lid designs. In high-traffic conference or collaboration spaces, this is the correct choice — a pop-up style cover is more appropriate only where frequent, repeated access is the priority.
• Un-Prewired Configuration: The 6AT2GY ships without pre-installed modules or outlets, so the integrator selects and installs exactly the data, power, and AV inserts the project requires. No stripping out unwanted pre-populated modules, no compatibility guesswork — you spec the fill, you install the fill.
• Gray (GY) Finish: The gray colorway coordinates with standard commercial carpet tile and polished concrete floors. For installations requiring a closer color match to tile or hardwood finishes, confirm the finish selection before rough-in — swapping a cover post-pour is significantly more disruptive than selecting the right color at the RFP stage.
• TAA Compliant: The 6AT2GY carries TAA (Trade Agreements Act) compliance, making it eligible for federal, state, and municipal government procurement where TAA compliance is a contract requirement. Verify your project's specific FAR clause requirements, but this unit clears the baseline TAA hurdle.
• Overall Installed Footprint — 11.5" × 11.5" × 19.5": The 292.1 × 292.1 × 495.3 mm overall envelope (including the below-floor canister at 16.25" depth) dictates your core-cut dimensions and the minimum floor-void clearance required. Confirm 19.5" of clear depth below the finished floor surface before specifying — shallow raised-access floors with 12–14" void heights cannot accommodate this unit without structural modification.
• 7.75" × 7.25" Body Dimensions: The 7.75" width and 7.25" height of the device body (19.7 × 18.4 cm) determine the core-cut aperture in the slab. Coordinate these dimensions with the structural engineer and flooring contractor early — a mis-sized core cut in a post-tension slab is an expensive correction.
• 16.25" Below-Floor Canister Depth: At 41.3 cm deep, the canister requires meaningful void space below the slab or access floor. Standard 18" raised-access floors typically provide adequate clearance; slab-on-grade installations require a sleeve and below-grade pocket, which must be planned at the concrete pour stage — not during finish work.
• Evolution 6AT2 Series Platform: As part of Middle Atlantic's Evolution 6AT2 line, this device is designed to accept a range of compatible power, data, and AV inserts from the same product family. Module compatibility is series-specific — verify insert compatibility against the 6AT2 series module list before procuring fills separately.

Integration & Compatibility

The 6AT2GY is part of Middle Atlantic's recessed floor cable management and poke-through device ecosystem. Because it ships un-prewired, it accepts field-installed inserts for power (standard duplex or TR receptacles), low-voltage data (keystone jacks, brush plates), and AV connectivity (HDMI, USB-A/C, HDBaseT) — all sourced separately and matched to the 6AT2 series module format.

In AV-over-IP and structured AV infrastructure deployments, poke-throughs like the 6AT2GY typically terminate at a nearby wall plate, floor box hub, or directly to a PoE network switch via Cat6A homerun. Conduit sleeves through the canister body allow clean cable management from below the floor to the device's insert field — coordinate conduit sizing with the cable schedule before rough-in.

TAA compliance makes the 6AT2GY suitable for government facility AV integrations where country-of-origin requirements apply to all installed infrastructure components, not just active electronics.

Frequently Asked Questions

Q: Is the Middle Atlantic 6AT2GY TAA compliant?

A: Yes. The 6AT2GY is TAA (Trade Agreements Act) compliant, making it eligible for federal, state, and local government procurement contracts that require TAA compliance. Verify the specific FAR clause in your contract for any additional requirements.

Q: Does the 6AT2GY come prewired with outlets or data ports?

A: No. The 6AT2GY ships un-prewired. Inserts for power, data, and AV connectivity are selected and installed separately by the integrator, giving full control over the port configuration for each specific project.

Q: What is the minimum floor void depth required to install the 6AT2GY?

A: The overall installed depth is 19.5 inches (495.3 mm), with the below-floor canister measuring 16.25 inches (41.3 cm). You need at least 19.5 inches of clear void below the finished floor surface. Standard 18-inch raised-access floors may be insufficient — verify actual clearance before specifying.

Q: What is the core-cut size needed for the 6AT2GY?

A: The device body measures 7.75 inches wide by 7.25 inches tall (19.7 × 18.4 cm). Use these dimensions to size the core cut in the slab or floor panel. Coordinate with the structural engineer before cutting, particularly in post-tension concrete.

Q: What color is the 6AT2GY cover?

A: The cover is gray (GY suffix in the model number). If your finished floor requires a different color match, verify alternative finish options within the Evolution 6AT2 series before rough-in — changing the cover color after installation is straightforward, but changing the canister is not.

Q: Is the 6AT2GY compatible with other Middle Atlantic Evolution 6AT2 series inserts?

A: Yes. The 6AT2GY is part of the Evolution 6AT2 series platform, designed to accept compatible power, data, and AV module inserts from that series. Verify specific insert compatibility against the 6AT2 series module list — not all inserts from other Middle Atlantic series are cross-compatible.

The spec that ends most 6AT2GY conversations before they start is the 19.5-inch overall installed depth — and that number comes up fast once you pull the floor plans. On a slab-on-grade building or a raised-access floor with a shallow 12-inch void, the 6AT2GY simply won't fit without structural modification, and that's a conversation you want to have at design development, not during punch-list. If the void clears 19.5 inches, the 6AT2GY is a clean, un-prewired canvas that gives your team full control over the insert mix.

Technical Highlights:

• 19.5" Overall Depth (495.3 mm): This is the governing spec for site feasibility. Measure actual floor void clearance — not nominal floor system depth — before specifying. Account for any structural members, conduit, or plenum fill that reduce usable void height.
• 7.75" × 7.25" Body (19.7 × 18.4 cm): The core-cut dimensions are non-negotiable once the slab is poured. Issue these numbers to the structural engineer and flooring sub at the earliest possible coordination meeting — a mis-sized or mis-located core cut in post-tension concrete is a major change order.
• TAA Compliant: Government AV integrations increasingly require TAA compliance across all installed infrastructure, not just the active electronics. The 6AT2GY clears that requirement at the passive infrastructure layer, which simplifies procurement paperwork on GSA schedule and SLED projects.

Deployment Considerations:

• The un-prewired configuration means every insert is a separate line item — budget and schedule accordingly. Sourcing 6AT2 series-compatible power and data modules from the same procurement as the canister avoids compatibility surprises during trim-out.
• The flush cover style is not a pop-up: it does not provide quick, frequent access without tools. If the use case involves daily cable connect/disconnect by end users (laptop docking, presentation AV), a pop-up or flip-lid variant may be the more practical choice — the flush style is optimized for permanent or semi-permanent cable runs where aesthetics outweigh access convenience.

The 6AT2GY fits best in high-finish commercial environments — federal office build-outs, corporate boardrooms, university collaboration spaces — where TAA compliance is contractual, floor aesthetics are a design priority, and the cable infrastructure is set at move-in rather than reconfigured daily.
