Middle Atlantic EFB45CTGY Evolution Series Floor Box Flush Cover Insert Gray

Overview

The Middle Atlantic EFB45CTGY is the flush cover insert for the Evolution Series (EVO) EFB45 raised floor box — the finishing piece that brings a low-profile, surface-flush closure to commercial AV and security infrastructure deployments where a clean floor presentation matters. At 9.94 inches wide (25.2 cm) and just 1.19 inches tall (3 cm), the EFB45CTGY sits nearly flush with surrounding flooring, eliminating the raised-lid profile that creates trip hazards and snag points in high-foot-traffic environments like conference centers, operations floors, trading rooms, and large open-plan offices.

This insert is gray (GY suffix) and ships as the cover component specifically matched to the EFB45 floor box platform within Middle Atlantic's Middle Atlantic AV infrastructure line. If your project spec calls for the EFB45 box with a flush finish, the EFB45CTGY is the correct cover variant — not the lift-lid or angled-access alternatives that appear elsewhere in the EVO floor box family.

Key Features

• Flush Cover Style: The flush design keeps the cover surface coplanar with the surrounding floor tile or raised-floor panel. In data centers, broadcast floors, and security operations centers where cable runs terminate at floor level, a protruding lid creates a real housekeeping and ergonomic problem — the EFB45CTGY eliminates that by sitting flat.
• 9.94-inch Width (25.2 cm): Sized to match the EFB45 floor box footprint exactly. Verify your box model before ordering — the EVO family includes multiple box sizes and cover dimensions are not interchangeable across the line.
• 1.19-inch Profile (3 cm): The low-stack height is a practical advantage in raised-floor environments where plenum clearance is managed tightly. Less vertical intrusion above the subfloor panel means fewer conflicts with adjacent cable management and easier panel removal during moves and changes.
• Standard Receptacle Type: Configured for standard receptacle cutouts, compatible with the EFB45's standard module population. If your floor box is fitted with keystone modules, Decora inserts, or specialty AV connectors, confirm the receptacle format matches before specifying this cover.
• Gray (GY) Finish: Neutral gray coordinates with typical raised-floor tile finishes and commercial carpet tile in data center and operations center environments. Middle Atlantic offers the EVO cover in other finishes — specify GY explicitly if gray is the project requirement.
• TAA Non-Compliant: The EFB45CTGY is not TAA compliant. For federal government projects, GSA Schedule orders, or any procurement vehicle with a Trade Agreements Act requirement, this cover insert cannot be specified. Verify project compliance requirements before purchasing — do not substitute a non-TAA part on a TAA-required job.

Integration & Compatibility

The EFB45CTGY is a replacement or completion cover insert for the Middle Atlantic EVO EFB45 raised floor box platform. It is not a standalone product — it requires the matching EFB45 floor box body to install. When specifying complete floor box assemblies for an AV or security infrastructure project, pair this cover with the correct EFB45 base and the appropriate cable management and power module inserts for your connector complement.

For integrators specifying floor infrastructure across a full facility build-out — particularly in security operations centers, network operations centers, or AV-integrated conference environments — the EVO floor box line works alongside Middle Atlantic's rack and enclosure ecosystem. Review the EVO series product family to confirm cover-to-box pairing before finalizing your bill of materials.

Internal cable routing, grounding provisions, and module compatibility are determined by the floor box body, not this cover. Confirm all functional requirements at the box level; the EFB45CTGY is strictly the cover insert.

Frequently Asked Questions

Q: What floor box does the EFB45CTGY cover fit?

A: The EFB45CTGY is the flush cover insert designed for the Middle Atlantic EVO Series EFB45 raised floor box. It is not interchangeable with other EVO box sizes — confirm the EFB45 box model before ordering.

Q: Is the EFB45CTGY TAA compliant for government procurement?

A: No. The EFB45CTGY is not TAA compliant. It cannot be used on federal projects, GSA Schedule orders, or any procurement requiring Trade Agreements Act compliance.

Q: What color is the EFB45CTGY?

A: Gray. The GY suffix in the model number designates the gray finish. Middle Atlantic offers EVO floor box covers in other finishes — specify EFB45CTGY explicitly for gray.

Q: What is the cover profile height?

A: The EFB45CTGY measures 1.19 inches (3 cm) in height, providing a low flush profile suited for raised-floor environments where plenum clearance is managed carefully.

Q: What receptacle type does the EFB45CTGY support?

A: The EFB45CTGY is configured for standard receptacle cutouts, matching the EFB45 floor box's standard module format. Verify your module population matches before specifying this cover.

The EFB45CTGY is one of those spec-line items that looks trivial until you're standing in a half-finished SOC or data center floor and realize the cover you ordered is the wrong size or wrong style for the box already in the deck. The flush cover style is the right call for nearly every occupied workspace — the 1.19-inch (3 cm) profile keeps the box out of the way underfoot, and the 9.94-inch footprint (25.2 cm) is matched to the EFB45 body, not a universal fit.

Technical Highlights:

• Flush Cover Style: Coplanar with the floor surface — no raised edge to snag cables or create trip risk in high-traffic operations environments.
• 1.19-inch Height: At 3 cm profile, this cover adds minimal vertical stack above the subfloor panel, which matters in tight plenum sections where raised-floor tiles have limited clearance for protruding hardware.
• 9.94-inch Width: Matched to the EFB45 box footprint. Cross-referencing the full EVO line before ordering prevents the common mistake of pairing a cover from a different box tier.

Deployment Considerations:

• The EFB45CTGY is a cover insert only — all functional decisions (module type, power, connectivity) are made at the EFB45 box level. Don't order the cover until the box configuration is locked.
• TAA non-compliance is a hard stop for federal or GSA projects. There is no field workaround — if the project requires TAA, a different part number is needed from the outset.

Best fit for commercial security operations centers, broadcast floors, and enterprise conference infrastructure where a clean, low-profile floor finish is specified and the EFB45 box is already in the BOM.
