Middle Atlantic EFB45CTBKTR Evolution Series Flush Floor Box Cover Insert

Overview

The Middle Atlantic EFB45CTBKTR is a flush-mount floor box cover insert designed for the Evolution Series EFB45 raised floor box platform. At 9.94 inches wide and just 1.19 inches in profile height, this black cover sits flush with finished flooring surfaces — eliminating trip hazards while maintaining clean aesthetics in open-plan offices, boardrooms, and commercial AV integration projects. If you're finishing out a raised-floor installation and need a cover that doesn't interrupt the floor plane or draw attention, the EFB45CTBKTR is the correct cap for that box.

The cover ships in black and is purpose-built for the EFB45 floor box family from Middle Atlantic's AV infrastructure line. It is not a universal fit — confirm your floor box model before ordering.

Key Features

• Flush Cover Style: the 1.19-inch height sits level with the surrounding floor surface rather than projecting above it. In high-traffic commercial spaces, flush terminations reduce tripping liability and pass ADA-sensitive walkway requirements more cleanly than raised covers.
• Tamper-Resistant Receptacle Type: the insert uses tamper-resistant (TR) receptacles, which require simultaneous pressure on both slots to open. In environments accessible to non-technical staff, visitors, or students, TR outlets are a code requirement in many jurisdictions — this cover ships compliant out of the box rather than requiring a field swap.
• 9.94-Inch Width: sized to the EFB45 form factor. The 9.94-inch (25.2 cm) footprint provides enough face area to accommodate the standard receptacle and connector layout of the Evolution Series box without crowding cable egress.
• Black Finish: matches dark hardwood, polished concrete, and commercial carpet tile installations where a silver or grey cover would create a visible contrast. Order the correct color at initial install — refinishing floor covers in the field is not practical.
• Low-Profile 1.19-Inch Height: at 3 cm tall, the cover adds minimal stack height above the subfloor. Relevant when raised floor panels have limited clearance tolerance or when finished floor height is constrained by door thresholds and transitions.
• TAA Compliance Status — Not Compliant: the EFB45CTBKTR is confirmed TAA non-compliant per manufacturer data. Government, federal, and GSA-schedule projects with TAA requirements should verify an alternative SKU — do not assume compliance without checking the specific part number.

Integration and Compatibility

The EFB45CTBKTR is engineered as a replacement or finishing cover for the Evolution Series EFB45 raised floor box platform. It is not a standalone electrical component — it requires an installed EFB45 box beneath it to function. Integrators specifying this cover should cross-reference the base box model to confirm cover-to-box compatibility before procurement.

The tamper-resistant receptacle configuration aligns with NEC 406.12 requirements for commercial occupancies. Confirm local code applicability with your AHJ, as requirements vary by jurisdiction and occupancy type. For projects requiring AV infrastructure planning, pairing this cover with the correct base box and power/data inserts at the spec stage avoids costly field-order corrections.

For raised-floor AV installations, this cover works alongside Middle Atlantic rack and enclosure systems where floor-level power and data distribution feeds equipment racks in open or semi-open floor plans.

Frequently Asked Questions

Q: Is the EFB45CTBKTR compatible with any floor box, or only the Middle Atlantic EFB45?

A: The EFB45CTBKTR is designed specifically for the Middle Atlantic Evolution Series EFB45 floor box platform. It is not a universal cover. Confirm your installed base box model before ordering.

Q: Is the EFB45CTBKTR TAA compliant for government projects?

A: No. Manufacturer data confirms the EFB45CTBKTR is not TAA compliant. Projects subject to TAA requirements — federal, GSA schedule, or DoD — should specify an alternate SKU.

Q: What color does the EFB45CTBKTR ship in?

A: Black. The cover is black finish, 9.94 inches wide. If your installation requires a different finish, verify available color variants in the EFB45 cover family before ordering.

Q: What does 'tamper-resistant' mean for the receptacle in the EFB45CTBKTR?

A: Tamper-resistant (TR) receptacles require simultaneous pressure on both contact slots before they open. This prevents objects from being inserted into a single slot accidentally or intentionally. TR outlets are required by NEC 406.12 in most commercial and residential occupancies — the EFB45CTBKTR ships with TR receptacles already built in.

Q: How tall is the EFB45CTBKTR above the floor surface?

A: 1.19 inches (3 cm). The flush cover style is designed to sit at or near floor level, minimizing the profile above the finished floor surface.

Q: Can the EFB45CTBKTR be used in a new installation or only as a replacement cover?

A: Both. It is the finishing cover for the EFB45 box — used in new installations to complete the floor box assembly and as a field replacement cover for existing EFB45 installations.

Ted Perry

The EFB45CTBKTR is a detail that gets overlooked in specs and creates problems during punch-list. That 1.19-inch flush profile is not decorative — it's the difference between a floor outlet that passes a facilities walkthrough and one that generates a field RFI about trip-hazard clearance. When I spec raised-floor AV distribution in open office or boardroom environments, the cover selection happens at the same time as the base box, not as an afterthought on the closeout order.

Technical Highlights:

• Flush Cover at 1.19 in (3 cm): sits level with finished floor surfaces — critical in high-foot-traffic commercial spaces where raised cover edges create liability and fail facilities inspection in occupied buildings.
• Tamper-Resistant Receptacles: ships NEC 406.12-aligned TR outlets standard, eliminating a common field correction on commercial CO inspections where TR is mandatory and a standard receptacle cover was spec'd by mistake.
• 9.94-Inch (25.2 cm) Width: purpose-sized to the EFB45 platform — no field trimming, no adapter plates, no improvised gaskets. The fit is direct and the finish line is clean.

Deployment Considerations:

• Confirm the installed base box is the Middle Atlantic EFB45 before ordering — this cover does not adapt to other manufacturers' floor box footprints, and a mis-ordered cover on a closeout schedule is a costly delay.
• TAA non-compliance is confirmed for this SKU — any project with a federal, GSA, or government end-user clause needs to be re-spec'd to a compliant alternate before the order is placed, not after delivery.

Best fit: commercial AV integration in corporate offices, higher education conference rooms, and hospitality venues running raised-floor power and data distribution where flush termination and code-compliant TR outlets are both non-negotiable finish requirements.
