Wiremold Middle Atlantic EFB45BTCGY Evolution Series Floor Box Surface Cover Solid Lid Gray

Overview

The Middle Atlantic EFB45BTCGY is a replacement and finishing cover for the Evolution Series EFB45 raised floor box system — the piece that sits flush at floor level and protects the receptacle cavity when the box is closed. At 9.94 in wide and 13.75 in deep with a low-profile 1.19 in height, it keeps cable pathways and power outlets accessible in raised-floor environments like data centers, control rooms, broadcast studios, and boardrooms without creating a tripping hazard or an exposed junction. The solid-lid style means the receptacle area is fully covered when not in active use — no exposed ports, no debris ingestion, no snagged cabling.

Key Features

• Surface Cover Style: The surface-mount profile seats directly on the raised floor tile around the box opening. No recessing required — this simplifies retrofit installs where cutting deeper into the tile is not an option or the subfloor clearance is limited.
• Solid Lid: A fully closed lid protects receptacles from foot traffic, spills, and dust accumulation when not in use. In mission-critical rooms where cleanliness and cable management standards matter (data center hot aisles, 24/7 NOC floors), that protection extends the service life of the outlets below.
• Compact Low-Profile Height (1.19 in / 3 cm): At just over an inch of rise above the floor surface, the EFB45BTCGY does not create a meaningful step edge. That matters for AV and security integration environments where rolling equipment (AV carts, server dollies) or regular foot traffic cross the floor constantly.
• 9.94 in x 13.75 in Footprint: Sized specifically for the EFB45 box platform — this is not a universal cover. Verify your existing floor box is the EFB45 series before ordering. The precise fit ensures proper seating, gasket compression if applicable, and correct alignment of any internal receptacle cutouts.
• Gray Finish: The neutral gray color coordinates with standard commercial raised-floor tile finishes (typically gray or charcoal). Avoids the visual mismatch of a black cover against a light tile field — a detail integrators notice on high-visibility installs like boardrooms and executive briefing centers.
• Standard Receptacle Type: Compatible with standard receptacle configurations in the EFB45 platform — no proprietary outlet modules required. Supports the typical power and data receptacle combinations used in Middle Atlantic floor box deployments.
• TAA Compliant: No: This cover is not TAA-compliant. If your project is a federal installation, GSA schedule purchase, or any contract requiring TAA compliance for all components including covers and accessories, confirm compliance requirements extend to covers before specifying. Non-federal commercial installs are unaffected.

Integration and Compatibility

The EFB45BTCGY is designed exclusively for the Middle Atlantic Evolution Series EFB45 raised floor box platform. It is not a universal floor box cover. Confirm your box model is EFB45-series before ordering. The cover works with standard receptacle modules in that platform — power, data, and AV interface modules supported by the EFB45 base unit seat correctly under this lid. For installations planning a full floor box deployment from scratch, pair this cover with the matching EFB45 base unit and the appropriate power and data modules for your room's connectivity requirements.

Frequently Asked Questions

Q: Is the EFB45BTCGY compatible with all Middle Atlantic floor boxes?

A: No. The EFB45BTCGY is sized specifically for the Evolution Series EFB45 floor box platform (9.94 in x 13.75 in footprint). It is not a universal cover and will not fit other Middle Atlantic floor box models without verification of matching dimensions.

Q: What does the solid lid cover style mean — can you still access the receptacles?

A: The solid lid fully closes over the receptacle cavity when shut, protecting outlets from dust, debris, and foot traffic. To access the receptacles, the lid is opened or removed. This differs from a flip-lid or insert-style cover where individual ports remain partially exposed.

Q: Is the EFB45BTCGY TAA compliant?

A: No. Per the manufacturer's specification, this product is not TAA compliant. If your project requires TAA-compliant components throughout — including covers and accessories — verify compliance requirements with your contracting officer before specifying this SKU.

Q: Will the 1.19 in height of the EFB45BTCGY create a tripping hazard on a raised floor?

A: At 1.19 in (3 cm) above the floor surface, the cover has a low profile that minimizes trip risk in normal walking environments. However, any floor-level protrusion should be considered in the context of your room layout, ADA requirements, and equipment traffic patterns. Consult your facilities team on placement relative to walking paths.

Q: What color is the EFB45BTCGY?

A: Gray. The neutral gray finish is designed to blend with standard commercial raised-floor tile finishes common in data centers, control rooms, and corporate AV environments.

The EFB45BTCGY is the finishing detail that separates a clean raised-floor integration from a sloppy one. At 1.19 in of floor rise and a 9.94 x 13.75 in footprint matched exactly to the EFB45 platform, this cover is not a commodity part — it is a precision fit component, and ordering the wrong cover leaves you with a gap, a misaligned lid, or a cover that rocks on the tile edge.

Technical Highlights:

• Solid Lid Protection: Fully closes the receptacle cavity — keeps dust, spills, and debris out of the power and data outlets below. In 24/7 operations environments (NOCs, dispatch centers), that protection matters for outlet longevity.
• 1.19 in Profile: Low enough to stay below the threshold where most facilities teams flag a floor obstruction, while still providing a positive close over the box opening. Avoids the flush-tile look of a recessed cover where height clearance under the tile is not available.
• Gray Finish Coordination: Matches standard commercial raised-floor tile colorways. On a boardroom or briefing center floor where aesthetics are part of the spec, a mismatched cover color is the kind of detail that generates a punchlist item at closeout.

Deployment Considerations:

• Confirm your existing floor box is EFB45-series before ordering — the 9.94 x 13.75 in dimensions are platform-specific, not universal. A mismatch means a non-seating cover and a return.
• TAA compliance is explicitly listed as No on this SKU. Any federal, GSA, or DoD project that extends TAA requirements to ancillary components including covers needs a compliant alternative — do not assume covers are exempt without checking your contract terms.

Best fit: boardrooms, executive briefing centers, and control rooms on commercial raised-floor systems where the EFB45 base is already specified and the finish detail needs to match the room aesthetic at project closeout.
