Middle Atlantic EFB45BTCBKTR Tamper-Resistant Surface Floor Box Cover

Overview

The Middle Atlantic EFB45BTCBKTR is a surface-mount floor box cover designed for the Evolution Series EFB45 raised floor box system. At 9.94 inches wide and 1.19 inches tall, this low-profile black cover sits flush enough for high-traffic areas while providing tamper-resistant receptacle protection — the kind of detail that matters in conference rooms, open office floors, and AV-integrated meeting spaces where both aesthetics and security are on the spec sheet. If you're finishing out an Middle Atlantic floor box installation and need a surface cover with TR outlets, this is the part.

Key Features

• Tamper-Resistant Receptacles: TR-rated outlets block foreign object insertion — required by NEC 406.12 in commercial and educational occupancies, and a practical safeguard in any space with foot traffic or public access. Specifying TR here avoids a common field inspection failure point.
• Surface Cover Style: Surface-mount configuration means the cover sits on top of the raised floor box rather than recessing flush. This simplifies retrofit installations where the floor construction doesn't accommodate a fully recessed lid — you get a finished appearance without requiring precise floor cutout depth matching.
• 9.94-Inch Width: The 9.94 in (25.2 cm) footprint matches the EFB45 series box dimensions. Confirm your floor box model before ordering — this cover is sized for the EFB45 platform and won't fit narrower single-gang enclosures.
• 1.19-Inch Profile: At 1.19 in (3 cm) tall, the EFB45BTCBKTR sits low enough to avoid creating a trip hazard in pedestrian zones. Still, confirm ADA and local code requirements for your specific floor application, as raised covers in high-traffic aisles may require additional signage or beveled transition strips depending on jurisdiction.
• Black Finish: The black colorway integrates cleanly into dark-floored boardrooms, tiered auditoriums, and AV-forward conference environments where silver or grey covers would stand out. Purely aesthetic, but a spec integrators and interior designers routinely specify when matching finish materials.
• TAA Compliance: This SKU is not TAA compliant. If your project is a federal contract, GSA schedule purchase, or any government procurement requiring TAA-compliant components, this cover does not qualify — source the TAA variant instead. This is a hard stop for federal work, not a minor note.

Integration & Compatibility

The EFB45BTCBKTR is part of Middle Atlantic's Evolution Series floor box ecosystem. It is designed to pair with the EFB45 raised floor box body. For AV and IT infrastructure buildouts, Middle Atlantic floor boxes are commonly specified alongside power distribution components and structured cabling pathways — the floor box serves as the termination point for power, data, and AV signal runs under raised access flooring. Verify that your floor box body, insert module, and cover are all specified from the EFB45 family to ensure fit and finish compatibility. Review the floor boxes and accessories category for companion components including inserts, bezels, and box bodies. If you are working on a government or federally funded project, consult the TAA status of every component in the assembly — this cover is explicitly non-TAA, which can disqualify an otherwise compliant system.

Frequently Asked Questions

Q: What floor box body does the EFB45BTCBKTR cover fit?

A: The EFB45BTCBKTR is designed for the Middle Atlantic Evolution Series EFB45 raised floor box. Confirm box model compatibility before ordering — the 9.94-inch width is specific to the EFB45 platform and will not fit narrower or different-series enclosures.

Q: Is the EFB45BTCBKTR TAA compliant?

A: No. The EFB45BTCBKTR is not TAA compliant. It cannot be used on federal government contracts or GSA schedule purchases requiring TAA-compliant components. If your project requires TAA compliance, you will need to source an alternate SKU.

Q: What does tamper-resistant mean on this floor box cover?

A: Tamper-resistant (TR) receptacles include internal shutters that prevent insertion of foreign objects into a single slot — both slots must be engaged simultaneously, as with a standard plug. This is required by NEC 406.12 in many commercial and educational installations and provides a baseline safeguard in occupied or public-access spaces.

Q: Is this a surface mount or flush mount cover?

A: The EFB45BTCBKTR uses a surface cover style, meaning it sits on top of the floor box rather than recessing flush with the finished floor surface. This is a relevant detail for retrofit installations and for verifying that the installed height (1.19 in / 3 cm) meets local code requirements for walkable floor surfaces.

Q: What color is the EFB45BTCBKTR?

A: Black. The cover is finished in black, making it a natural fit for dark-floored AV environments, boardrooms, and tiered presentation spaces where a black floor box finish is specified.

Eden Phillips

When I specify the EFB45BTCBKTR for a conference room or AV-integrated floor installation, the detail I flag first is the tamper-resistant receptacle type combined with the surface cover style — that combination tells me this cover is going into an occupied, finished space where both code compliance and aesthetics are active requirements, not afterthoughts.

Technical Highlights:

• Surface Cover Style: Sits on top of the EFB45 box body at 1.19 in (3 cm) total height — enough clearance for standard insert modules without requiring a flush floor cut. Simplifies retrofit work on existing raised floors.
• 9.94-Inch Width: Dimensioned specifically for the EFB45 series (25.2 cm). Do not substitute this cover onto a different-generation or different-width floor box body — fit is not interchangeable across series.
• TAA Status — Non-Compliant: Explicitly not TAA compliant. This is the single most common spec oversight on mixed commercial/government projects. Flag it at design review, not during procurement.

Deployment Considerations:

• Confirm the EFB45 box body and insert modules are already specified before ordering this cover — the cover ships without inserts, and the assembly only makes sense as a complete EFB45 system build.
• At 1.19 in above floor level, verify that local ADA and building code requirements for raised floor elements are met for your specific application, particularly in high-foot-traffic or accessible routes.

The EFB45BTCBKTR is the right finish component for a Middle Atlantic EFB45 raised-floor AV infrastructure build in a corporate boardroom or higher-education tiered classroom where TR receptacles are code-required and black finish is on the interior spec sheet.
