Middle Atlantic EFB45BTBK EVO Series Flush Solid Floor Box Cover — Black

Overview

The Middle Atlantic EFB45BTBK is a flush-style solid lid cover designed for the EVO Series EFB45 raised floor box, providing a clean, low-profile finish in open-office, conference room, and AV/IT infrastructure environments. At just 1.19 inches in height and 9.94 inches wide, this cover sits nearly flush with the floor surface — a critical detail in high-traffic areas where a raised lip creates a trip hazard or conflicts with furniture placement. The black finish blends with standard commercial flooring tiles and cable management aesthetics common in structured cabling installations.

If you are deploying Middle Atlantic floor infrastructure in a raised-floor environment and need a solid (non-populated) cover option — whether to blank unused ports or maintain a finished appearance on inactive runs — the EFB45BTBK is the purpose-built match for the EFB45 floor box chassis.

Key Features

• Flush cover style (1.19 in profile): The near-zero rise above floor level eliminates trip-hazard concerns in high-traffic boardrooms, trading floors, and AV presentation spaces where rolling chairs and foot traffic are constant. A raised cover in those environments is a liability; this one is not.
• 9.94-inch width matches EFB45 chassis: Dimensioned specifically for the EFB45 raised floor box — you get a precise fit without shimming, trimming, or adapting. Mismatched covers leave gaps that accumulate debris and look unfinished in professional installs.
• Solid lid design: No cutouts, no receptacle openings. Use this when a floor box location is temporarily or permanently unused — keeps the box protected from dust ingress and spills without pulling the box from the floor. Useful during phased buildouts where cabling is roughed in but not yet active.
• Standard receptacle type: Compatible with standard receptacle configurations in the EFB45 family — no special tooling or adapters required for installation or future conversion to a populated cover.
• Black finish: Coordinates with dark commercial carpet tile, polished concrete, and raised access flooring common in enterprise and broadcast environments. Avoids the visual noise of a mismatched silver or beige cover on a dark floor plane.
• TAA compliance status (No): This cover is not TAA-compliant. If your project is subject to federal procurement requirements or GSA schedule compliance, verify with your contracting officer before specifying — a non-compliant cover on a government build can flag an otherwise clean BOM.

Integration & Compatibility

The EFB45BTBK is designed for use with the Middle Atlantic EVO Series EFB45 raised floor box. It is not a universal floor box cover — fit and finish depend on the EFB45 chassis geometry. If you are building out a Middle Atlantic AV or power infrastructure rack room or open-plan workspace, confirm your floor box model before ordering this cover. For populated configurations requiring power or data inserts, a different cover variant with cutouts will be required. Consult the raised floor box accessories lineup for insert-compatible covers.

Frequently Asked Questions

Q: Is the EFB45BTBK TAA compliant?

A: No. The EFB45BTBK is not TAA compliant. Federal or GSA-regulated projects should verify procurement requirements before specifying this cover.

Q: What floor box chassis does the EFB45BTBK fit?

A: The EFB45BTBK is purpose-built for the Middle Atlantic EVO Series EFB45 raised floor box. It is not a universal cover — verify chassis compatibility before ordering.

Q: What does the solid lid design mean — no inserts at all?

A: Correct. This is a blank, solid cover with no receptacle openings. It is used to close and protect unused floor box locations. If you need power or data pass-through, a different cover variant with insert cutouts is required.

Q: What are the dimensions of the EFB45BTBK?

A: The cover measures 9.94 inches (25.2 cm) wide and 1.19 inches (3 cm) in height above floor level.

Q: Can this cover be used on any raised floor box?

A: No. It is specifically dimensioned for the EFB45 chassis. Using it on a non-EFB45 floor box may result in poor fit, gaps, or improper seating.

Karl Wilson

The EFB45BTBK is the cover you specify when a floor box location needs to be closed out cleanly — not a stopgap, but a purpose-fit solid lid for the EFB45 chassis that sits at just 1.19 inches above floor level. In my experience finishing out open-plan office buildouts and broadcast control rooms, the difference between a flush cover and a raised one shows up immediately in walkthrough inspections and, more importantly, in occupant complaints six months later.

Technical Highlights:

• 1.19 in flush profile: At just over an inch of rise, this cover presents minimal trip hazard in high-traffic zones — the right call for conference centers and trading floors where compliance officers and facility managers scrutinize floor hardware.
• 9.94 in chassis-matched width: Sized to the EFB45 footprint specifically, meaning no field trimming, no visible gaps at the perimeter, and a finished appearance that holds up to close inspection in architectural spaces.
• Solid lid, no cutouts: Protects the box interior from dust and debris during phased construction or long-term inactive runs — preserving the installed box for future activation without pulling it from the floor.

Deployment Considerations:

• Confirm the installed floor box is the EFB45 chassis before ordering — this cover is not dimensionally interchangeable with other Middle Atlantic or third-party floor box lines.
• The EFB45BTBK carries no TAA compliance designation. On any federal, state, or GSA-schedule project, a non-compliant floor cover can flag the entire infrastructure BOM if procurement is audited — address this at the spec stage, not at closeout.

This cover is the right spec for enterprise office buildouts, broadcast studios, and AV-integrated conference suites using the EFB45 raised floor box where inactive locations need a finished, durable, low-profile close-out rather than an open or temporarily plugged box.
