Middle Atlantic EFB45BTGY Evolution Series Flush Solid Floor Box Cover

Overview

The Middle Atlantic EFB45BTGY is the flush solid lid designed specifically for the Evolution Series EFB45 raised floor box platform. At 9.94 inches wide and just 1.19 inches tall, this gray cover sits flush with finished raised-floor surfaces — eliminating the trip hazard and ADA-compliance headaches that come with proud-mount or domed lids in high-traffic areas like conference rooms, trading floors, and AV integration environments.

This is a replacement or blank cover option within the EFB45 system: when a floor box location doesn't need active receptacles exposed — or when you're staging a box for future use — the EFB45BTGY provides a clean, professional close-out that protects the box cavity and maintains floor aesthetics. The solid lid means no open receptacle cutouts, keeping debris and liquids out of an otherwise exposed floor box.

Key Features

• Flush Cover Style (1.19 in / 3 cm height): sits level with the surrounding floor tile or panel surface. In high-foot-traffic environments — boardrooms, open trading areas, auditoriums — a flush profile eliminates the snag-and-trip risk that above-surface covers create, and satisfies ADA surface-level requirements where applicable.
• 9.94 in (25.2 cm) Width: matched to the EFB45 box footprint. This isn't a universal fit — verify you're covering an EFB45 series box before ordering. Attempting to retrofit onto a different-dimension box will result in gaps or non-flush seating.
• Solid Lid (No Receptacle Cutouts): fully blanks the box opening. Use this when the floor location is reserved for future cabling, when a box is being temporarily decommissioned, or when you need to protect the box cavity during construction phases before final terminations are made.
• Standard Receptacle Type: compatible with standard-format inserts within the Middle Atlantic Evolution Series ecosystem. Integrators already working within this platform won't need to source non-standard components.
• Gray (GY) Finish: matches common commercial raised-floor panel colors. In data centers and structured cabling environments where floor aesthetics matter for client-facing spaces, color-matching the cover to the floor panel is a detail that separates a polished installation from a rushed one.
• TAA Non-Compliant: the EFB45BTGY is not TAA compliant. If you're specifying for a federal government project or a contractor bound by TAA requirements, verify your procurement constraints before ordering — this cover will not satisfy those requirements.

Integration & Compatibility

The EFB45BTGY is purpose-built for the Evolution Series EFB45 raised floor box system. It is not a universal floor box cover — the 9.94-inch width and flush-mount geometry are specific to the EFB45 platform. If you're managing a mixed-floor environment with multiple box formats, confirm box series before sourcing covers. For active installations requiring power, data, or AV connectivity, the EFB45 system supports receptacle-equipped lids and inserts; the EFB45BTGY is the solid/blank variant within that family. Pair with appropriate cable management accessories when planning structured cabling runs to and from the floor box location.

Frequently Asked Questions

Q: What floor box series is the EFB45BTGY compatible with?

A: The EFB45BTGY is designed specifically for the Middle Atlantic Evolution Series EFB45 raised floor box platform. It is not a universal cover and should not be assumed to fit other floor box formats or manufacturers.

Q: Is the EFB45BTGY TAA compliant?

A: No. The EFB45BTGY is not TAA compliant. Federal projects or contracts requiring TAA-compliant components should verify alternative options before specifying this cover.

Q: What does 'solid lid' mean — are there any receptacle openings?

A: The solid lid has no receptacle cutouts. It fully blanks the floor box opening, making it suitable for protecting unused or future-use box locations, or for construction-phase protection before final terminations.

Q: What is the installed height of the EFB45BTGY above the floor surface?

A: The cover sits at 1.19 inches (3 cm) in height in flush configuration, designed to sit level with the surrounding raised-floor panel surface rather than proud of it.

Q: What color is the EFB45BTGY?

A: Gray (GY suffix). This finish is selected to match common commercial raised-floor panel colors in data center and structured cabling environments.

Karl Wilson

The EFB45BTGY is a detail part that integrators either spec correctly the first time or end up reordering — the 9.94-inch width is not a common dimension across competing floor box platforms, and a wrong-series cover on a job site means a visible gap or a non-flush seat that fails the close-out inspection. Get the box series confirmed before the order drops.

Technical Highlights:

• Flush Profile (1.19 in / 3 cm): in ADA-sensitive or high-traffic environments, a flush lid is non-negotiable — proud-mount covers in conference room or trading floor applications create code and liability exposure that a $20 cover swap doesn't justify.
• Solid Lid — No Cutouts: fully seals the EFB45 cavity; use during construction phases or for blanked-out locations where cabling is planned but not yet terminated — keeps debris and moisture out of the box until final fit-out.
• Gray (GY) Colorway: matches standard commercial raised-floor panel finishes; in client-facing data center or AV rooms, mismatched cover colors stand out — the GY variant aligns with the majority of installed access floor systems.

Deployment Considerations:

• Confirm the installed box is an EFB45 series unit before ordering — this cover is not cross-compatible with other Middle Atlantic or third-party floor box formats; a mismatch will require a return and delay close-out.
• TAA non-compliance is a hard stop for federal and GSA-contract work; flag this early in the specification phase rather than at submittal review.

Best fit for commercial AV integrations, structured cabling close-outs, and raised-floor data center environments where a clean, flush finish on inactive or staged floor box locations is required at final walk-through.
