Middle Atlantic EFB45CTBZTR Evolution Series Flush Floor Box Cover Insert

The Middle Atlantic EFB45CTBZTR is a flush-mount floor box cover insert designed for the Evolution Series EFB45 raised floor box platform. At 9.94 inches wide and just 1.19 inches in profile height, it sits nearly level with finished flooring — a practical requirement in AV presentation spaces, conference rooms, and open-plan office environments where protruding hardware creates both a trip hazard and an aesthetic problem. The bronze finish integrates naturally with wood, tile, and commercial carpet surround trims.

Overview

Floor box cover inserts are often an afterthought, but the wrong choice leads to repeated service calls: covers that catch on rolling chairs, receptacles that get tampered with in public spaces, or finishes that clash with room aesthetics. The EFB45CTBZTR addresses all three. The flush cover style means the insert sits at floor level rather than raised above it, reducing snag and trip risk in high-traffic areas. Tamper-resistant receptacles add a layer of access control without requiring separate outlet covers — relevant in classrooms, lobbies, and any space where unsupervised access to power outlets is a liability concern. The bronze colorway is a deliberate finish choice for environments where the standard white or black doesn't match the room's hardware palette. Note that this product is not TAA compliant, which matters for federal procurement — confirm your project requirements before specifying.

Key Features

• Flush Cover Style (1.19 in / 3 cm profile): The low-profile flush design keeps the insert nearly level with the finished floor surface. In boardrooms and presentation theaters where rolling chairs and foot traffic are constant, a protruding cover invites damage and liability — the flush mount eliminates that risk without requiring recessed subfloor work.
• Tamper-Resistant Receptacles: Built-in tamper resistance means the outlet requires simultaneous pressure on both slots to accept a plug — standard screwdrivers, keys, and other foreign objects are rejected automatically. In schools, healthcare waiting areas, or any space with public access, this removes the need for plug-in outlet covers that staff forget to reinstall.
• Bronze Finish: The bronze colorway covers situations where white or black standard finishes are wrong for the room. Hardwood floors, warm tile, and brass architectural hardware all pair with bronze better than neutral colors — this isn't a cosmetic luxury, it's the spec that prevents a facility manager from ordering a rework after installation.
• 9.94-Inch Width: Sized to fit the Evolution Series EFB45 floor box platform, the 9.94 in (25.2 cm) width accommodates standard dual-gang and multi-circuit layouts within the EFB45 footprint. Verify your floor box rough-in matches this insert width before ordering — the EFB45CTBZTR is not a universal-fit cover.
• 1.19-Inch Installed Height: At 3 cm above the floor box deck, the insert's finished height keeps clearance requirements minimal. This is relevant when specifying transition strips between flooring materials — low-profile inserts simplify that detail compared to taller pedestal-style covers.

Integration and Compatibility

The EFB45CTBZTR is purpose-built for the Middle Atlantic Evolution Series EFB45 raised floor box platform. If you are specifying a new floor box installation, pair this insert with the corresponding EFB45 enclosure. If you are replacing a cover on an existing install, confirm the rough-in box is an EFB45 — this insert is not backward-compatible with older Middle Atlantic floor box generations or third-party enclosures. For complete AV infrastructure planning, see the AV infrastructure planning guide to coordinate floor box placement with cable routing, power strips and modules, and finish hardware across the room.

Frequently Asked Questions

Q: Is the EFB45CTBZTR TAA compliant?

A: No. The EFB45CTBZTR is not TAA compliant. If your project requires TAA compliance for federal, state, or GSA procurement, verify this before specifying — you will need an alternate model.

Q: What floor box enclosure is the EFB45CTBZTR designed to fit?

A: The EFB45CTBZTR is designed specifically for the Middle Atlantic Evolution Series EFB45 raised floor box enclosure. It is not a universal cover and may not fit older Middle Atlantic generations or third-party floor boxes.

Q: What does the tamper-resistant receptacle type mean in practice?

A: Tamper-resistant receptacles require simultaneous insertion pressure on both slots to accept a plug. This prevents foreign objects — keys, screwdrivers, small fingers — from being inserted into a single slot, meeting the safety requirement for child- and public-accessible spaces without plug-in covers.

Q: What is the finished height of the EFB45CTBZTR above the floor surface?

A: The EFB45CTBZTR has an installed height of 1.19 inches (3 cm), making it a flush-style cover that sits nearly level with the surrounding flooring material.

Q: Can the EFB45CTBZTR be used in outdoor or wet locations?

A: The available specifications do not include an environmental or wet-location rating for this insert. It should be treated as an indoor, dry-location component unless Middle Atlantic documentation explicitly states otherwise.
