Middle Atlantic EFB45CTCBKTR Evolution Series Floor Box Cover with Surface Insert

The Middle Atlantic EFB45CTCBKTR is a raised floor box cover designed for the Evolution Series EFB45 floor box, providing a surface-mount, tamper-resistant finish point for AV, power, and data infrastructure in commercial environments. At 9.94 in (25.2 cm) wide and 1.19 in (3 cm) tall, it sits flush in raised-floor deployments without creating a trip hazard or interfering with rack-room cable management. If you're specifying floor connectivity for a conference room, operations center, or structured AV installation, this cover completes the floor box assembly with the correct receptacle profile for the application.

Key Features

• Surface Cover Style: The surface-mount profile sits at 1.19 in above the finished floor — enough clearance for clean connector access without the raised lip that snags cables or rolling carts in active work environments.
• Tamper-Resistant Receptacles: Tamper-resistant outlets require simultaneous pressure on both contact slots to accept a plug, blocking accidental or unauthorized insertion of foreign objects. This is the correct specification for any installation subject to NEC 406.12 requirements or where foot traffic includes non-technical personnel.
• 9.94 in (25.2 cm) Width: Sized to fit the EFB45 floor box footprint — verify your rough-in matches before ordering. This is not a universal cover; it is engineered to the EFB45 series dimensions.
• Black Finish: The black colorway integrates cleanly into dark carpet tile, polished concrete, or raised-floor tile environments common in data centers and broadcast control rooms without drawing attention to the floor infrastructure.
• TAA Compliance: No: This product is not TAA-compliant. Federal government projects or contracts with TAA requirements will need an alternate Middle Atlantic floor box solution. Confirm your project's procurement requirements before specifying.
• Evolution Series Integration: Designed as a matched component for Middle Atlantic's Evolution floor box line, ensuring correct dimensional fit, finish consistency, and compatibility with the EFB45 rough-in box — no field modification required.

Integration and Compatibility

The EFB45CTCBKTR installs as the finish cover on the raised floor box rough-in assembly. It is not a standalone product — the underlying EFB45 box must be installed and set to finished floor height before this cover is applied. Compatible insert types slot into the surface opening; verify insert selection against your power and data requirements independently. For AV infrastructure planning in conference rooms or huddle spaces, pair this with the appropriate Middle Atlantic insert module for your connector mix. If you are also specifying rack infrastructure, review Middle Atlantic's rack enclosure line for system-level consistency.

Frequently Asked Questions

Q: Is the EFB45CTCBKTR TAA compliant?

A: No. The EFB45CTCBKTR is not TAA compliant. Projects with federal procurement requirements should select a TAA-compliant alternative from the Middle Atlantic floor box line.

Q: What floor box does the EFB45CTCBKTR fit?

A: It is designed for the Middle Atlantic Evolution Series EFB45 floor box. The cover is dimensioned specifically for that rough-in — confirm your installed box model before ordering.

Q: What does the tamper-resistant receptacle designation mean?

A: Tamper-resistant receptacles require simultaneous pressure on both contact slots to accept a plug. This is an NEC 406.12 requirement in certain occupancy types and is appropriate anywhere non-technical personnel have access to the floor outlet.

Q: What are the dimensions of the EFB45CTCBKTR cover?

A: Width is 9.94 in (25.2 cm) and height (profile above floor) is 1.19 in (3 cm).

Q: Is this cover available in colors other than black?

A: The verified specification for EFB45CTCBKTR is black. Other color variants, if available in the Evolution Series line, carry different part numbers.

The EFB45CTCBKTR is a finish component, not a feature product — but getting this wrong costs you a rework trip. The 1.19 in surface profile is the detail that matters most on job sites where ADA or local code limits floor protrusion height; at under 1.25 in, this cover clears most thresholds without requiring a separate ADA-compliant cover plate. The tamper-resistant receptacle spec is the other decision point: if your AHJ or spec sheet calls for TR outlets at floor level, this is the correct part number for the EFB45 rough-in.

Technical Highlights:

• Surface Profile (1.19 in): Low-profile cover keeps floor penetration under the 1.25 in threshold common in ADA and code reviews for raised-floor commercial installs — reduces field variance risk.
• Tamper-Resistant Receptacles: Meets NEC 406.12 tamper-resistant requirement for applicable occupancy types; eliminates the need to swap receptacles post-install if an inspection flags standard outlets.
• EFB45-Specific Dimensioning (9.94 in wide): Engineered fit to the Evolution Series rough-in means no shimming, no field cutting, and no cover-gap issues that appear with generic aftermarket plates.

Deployment Considerations:

• Verify the rough-in box is the EFB45 series before ordering — this cover will not fit generic or competitor floor boxes at the same nominal size.
• TAA compliance is not supported on this SKU; government or GSA-schedule projects require a different part number from the Middle Atlantic Evolution line.

This cover is the right finish piece for operations centers, broadcast control rooms, and corporate conference spaces using Middle Atlantic EFB45 rough-ins where tamper-resistant outlets are required by code or spec — not a general-purpose floor cover for mixed-brand installations.
