Middle Atlantic Evotr Flbx Flcvr SLD BK - EFB45BTBKTR

Middle Atlantic EFB45BTBKTR Evolution Series Flush Solid Floor Box Cover

The Middle Atlantic EFB45BTBKTR is a flush-mount solid lid cover designed for the Evolution Series EFB45 raised floor box — the cap that finishes a raised-floor installation cleanly when active outlets need to be concealed or protected. At 9.94 in (25.2 cm) wide and just 1.19 in (3 cm) tall, it sits nearly flat with the floor surface, removing trip hazards and keeping unused box positions secured in open-plan offices, boardrooms, and access-controlled server floors.

Key Features

• Flush Cover Style (1.19 in profile): The near-zero height above the floor plane means pedestrian traffic and rolling equipment pass over the box position without snagging. This matters in aisles, presentation spaces, and anywhere ADA clearance or equipment movement is a concern.
• 9.94 in Width — Matched to EFB45 Footprint: The cover is dimensioned specifically for the EFB45 floor box footprint. Using a mis-sized cover risks gaps at the perimeter that collect debris, create uneven surfaces, or expose wiring — this part eliminates that risk by design.
• Tamper-Resistant Receptacle Type: The tamper-resistant designation means the cover interface is engineered to resist casual or unauthorized access to the box interior. Relevant in shared spaces — conference floors, open offices, classrooms — where box contents should not be accessible without intent and tooling.
• Black Finish (EFB45BTBKTR): The black colorway integrates with dark raised-floor tile finishes common in data centers, broadcast studios, and modern commercial interiors. The color is part of the model number (BK = black), so ordering EFB45BTBKTR gives you the correct finish without substitution risk.
• Solid Lid Design: A solid lid means no exposed ports or cutouts when the position is not in active use. This keeps dust, liquid, and debris out of the box cavity — relevant for environments with cleaning protocols or particulate exposure.

Integration and Compatibility

The EFB45BTBKTR is a cover component for the Middle Atlantic Evolution Series EFB45 floor box system. It does not add power or data capacity — it replaces or completes an existing box position. Verify your floor box model is EFB45-series before ordering; Middle Atlantic offers multiple floor box families with different footprint dimensions that are not interchangeable. The flush profile is designed for raised floor tile applications where the box sits recessed into the tile grid — it is not intended for surface-mount or poured-concrete applications.

TAA compliance is not applicable for this part (confirmed: TAA Compliant = No). Buyers with GSA or federal procurement requirements should verify TAA status of the complete floor box assembly, not this cover alone.

Frequently Asked Questions

Q: What floor box model is the EFB45BTBKTR designed to fit?

A: The EFB45BTBKTR is the flush solid lid cover for the Middle Atlantic Evolution Series EFB45 floor box. It is dimensioned for the EFB45 footprint (9.94 in / 25.2 cm wide) and is not interchangeable with other Middle Atlantic floor box families.

Q: Is the EFB45BTBKTR TAA compliant?

A: No. TAA compliance is confirmed as not applicable for this part. Federal or GSA procurement requiring TAA compliance should verify the complete floor box assembly separately.

Q: Does the EFB45BTBKTR include power or data inserts?

A: No. This is a solid lid cover only — it closes off and protects an EFB45 floor box position. It does not add power outlets, data ports, or other active components.

Q: What does the tamper-resistant designation mean for this cover?

A: The tamper-resistant receptacle type means the cover interface is designed to resist unauthorized access without appropriate tooling — relevant in shared or public-access spaces such as conference rooms, classrooms, and open office floors.

Q: Does the black finish (BK) match standard data center raised floor tiles?

A: The black color is specified for dark raised-floor tile finishes common in data center and broadcast environments. BK is encoded in the EFB45BTBKTR model number, confirming the finish at order time.

James Everett

The EFB45BTBKTR is the part integrators overlook until the final walkthrough — a 1.19 in flush solid lid that closes off an EFB45 floor box position and keeps the floor surface clean, safe, and tamper-resistant. I specify it whenever a floor box position is installed speculatively or will be inactive for an extended period; leaving a box open in a high-traffic conference floor is a liability, not a feature.

Technical Highlights:

• 1.19 in flush profile: Sits nearly level with the raised floor tile surface — rolling carts, chairs, and foot traffic clear it without snagging, which matters in presentation and ADA-sensitive environments.
• 9.94 in width (EFB45-matched): Dimensioned specifically for the EFB45 footprint; a correctly sized cover eliminates perimeter gaps that collect debris or expose the box cavity to liquid intrusion during floor cleaning.
• Tamper-resistant design: Deters casual access to the box interior without tooling — the right spec for shared conference floors, open offices, and any space where the box contents should stay secured between scheduled maintenance.

Deployment Considerations:

• Confirm your installed floor box is the EFB45 series before ordering — Middle Atlantic floor box families have different footprints and this cover is not cross-compatible with other Evolution Series models.
• TAA compliance is not certified for the EFB45BTBKTR; if your project has federal or GSA TAA requirements, verify at the complete assembly level, not this cover alone.

Best fit for data centers, broadcast studios, and commercial conference floors where raised-floor box positions need to be sealed off cleanly between active use — the black finish integrates with dark tile grids standard in those environments.
