Middle Atlantic EFB45BTCGYTR Evolution Series Floor Box Cover with Solid Lid

Overview

The Middle Atlantic EFB45BTCGYTR is a gray, surface-style solid lid cover designed for the Evolution Series EFB45 raised floor box. At 9.94 in wide and 1.19 in tall, it sits flush with minimal protrusion above the floor plane — a practical choice for open office floors, conference rooms, and structured cabling environments where a clean finish matters. The EFB45BTCGYTR ships in gray and pairs with tamper-resistant receptacles, which matters in spaces where unauthorized device connections are a liability concern.

This is an accessory cover unit, not a complete floor box assembly. Verify your existing EFB45 box model before ordering — the cover is sized for the EFB45 footprint and is not a universal fit across Middle Atlantic's broader Middle Atlantic floor box catalog.

Key Features

• Surface Cover Style: The surface-mount lid sits directly over the floor box opening without recessing into the floor. This means no tile cutout work for the cover itself — faster install, and the lid remains fully accessible for future outlet servicing.
• Tamper-Resistant Receptacle Compatibility: Designed to pair with tamper-resistant outlets, which have internal shutters that block foreign object insertion. Relevant for deployments in schools, healthcare facilities, or any space subject to NEC 406.12 tamper-resistant requirements.
• Gray Finish (Color Code GY): The neutral gray finish blends into standard commercial carpet tile and hard floor environments. Specify this variant when matching existing gray EFB45 installations — Middle Atlantic offers alternate colors in the EFB45 family for coordinated deployments.
• Compact Low-Profile Form: At 1.19 in tall and 9.94 in wide, the cover adds minimal height above the floor surface — reducing trip hazard exposure compared to taller legacy floor box lids. Relevant for high-traffic corridors and ADA-sensitive zones.
• TAA Status: The EFB45BTCGYTR is not TAA compliant. If your project requires TAA-compliant components under a GSA schedule or federal procurement vehicle, confirm with your contracting officer before specifying this part — and check Middle Atlantic's floor box accessories line for a TAA-qualified alternate.

Integration and Compatibility

The EFB45BTCGYTR is engineered for the Middle Atlantic Evolution Series EFB45 raised floor box. Confirm the box model number in your existing installation before purchasing this cover — mismatched covers are a common field error on floor box retrofits. This cover does not include receptacles; outlets and data inserts are ordered separately to match your specific power and data requirements. For structured cabling projects, pair with cable management accessories appropriate to the box's port configuration. Integrators running network infrastructure drops to floor boxes should verify insert compatibility at the box level, not just the cover.

Frequently Asked Questions

Q: Is the EFB45BTCGYTR TAA compliant?

A: No. The EFB45BTCGYTR is not TAA compliant. Federal projects requiring TAA-compliant components should evaluate alternate models in the Middle Atlantic EFB45 line.

Q: Does the EFB45BTCGYTR include receptacles?

A: No. This is a cover-only unit. Receptacles and data inserts are purchased separately to match your specific outlet and connectivity requirements.

Q: What floor box model does the EFB45BTCGYTR fit?

A: The EFB45BTCGYTR is designed for the Middle Atlantic Evolution Series EFB45 raised floor box. Verify your box model before ordering — it is not a universal-fit cover.

Q: What does the tamper-resistant designation mean for this cover?

A: The cover is compatible with tamper-resistant receptacles, which include internal shutters to prevent foreign object insertion. This is relevant for installations subject to NEC 406.12 requirements, such as schools and healthcare facilities.

Q: What color is the EFB45BTCGYTR?

A: Gray (color code GY). The neutral gray finish is suited for standard commercial floor environments. Alternate color options may be available in the EFB45 cover family.

Ted Perry

The EFB45BTCGYTR is a straightforward cover replacement for the EFB45 raised floor box — but the details that matter are the ones integrators skip: at 9.94 in wide and 1.19 in tall, this is a dimensionally specific part, and ordering the wrong cover for your box variant is one of the more avoidable field mistakes on a structured cabling retrofit. Gray finish, surface lid, tamper-resistant receptacle compatibility — if those three descriptors match your existing installation, this is your part.

Technical Highlights:

• Surface Cover Style: No floor tile modification needed for the cover itself — the lid sits over the box opening, which keeps replacement and future outlet servicing fast on a finished floor.
• 1.19 in Profile Height: Low-profile lid reduces trip hazard exposure in high-traffic areas. Relevant in open office and conference room deployments where floor boxes sit in pedestrian paths.
• Tamper-Resistant Receptacle Fit: Compatible with TR outlets required under NEC 406.12 in schools, childcare, and healthcare occupancies — specifying a non-TR cover in those environments is a code issue, not just a preference.

Deployment Considerations:

• Confirm the EFB45 box model in your existing install before purchasing — the EFB45BTCGYTR is sized for the EFB45 footprint, not the full Middle Atlantic floor box range.
• TAA non-compliance is a hard stop for GSA or federal contract work. Verify procurement requirements before spec'ing this part on government projects.

Best fit for commercial office, conference room, and education retrofits where an EFB45 box is already installed and the existing gray cover needs replacement or the installation is being completed with a matching lid finish.
