Middle Atlantic EVO FLR BX Flush CVR Insert BK - EFB45CTBK

Middle Atlantic EFB45CTBK EVO Series Flush Floor Box Cover Insert

The Middle Atlantic EFB45CTBK is a flush-style cover insert designed for the EVO Series EFB45 raised floor box, delivering a low-profile finish in corporate AV installations, control rooms, and conference environments where cable management infrastructure needs to disappear into the floor rather than call attention to itself. At 9.94 inches wide and just 1.19 inches in height, this black insert sits nearly flush with the raised floor surface — no trip hazard, no visual disruption, and no exposed wiring.

Overview

Raised floor environments in enterprise AV and security infrastructure require modular floor box components that balance functionality with finished aesthetics. The EFB45CTBK cover insert fills that role for the Middle Atlantic EVO Series floor box line, providing a standard receptacle opening with a clean flush profile. Whether you're finishing out a broadcast control room, a trading floor, or a corporate boardroom, the cover insert is the piece that makes the installation look intentional rather than improvised.

Key Features

• Flush cover style, 1.19 in profile: The cover sits at 1.19 inches (3 cm) above the floor plane — low enough to avoid becoming a trip hazard in high-traffic areas while still providing accessible receptacle access. This matters in environments like open-plan trading floors or conference rooms where foot traffic crosses cable zones constantly.
• 9.94 in width (25.2 cm): Sized specifically for the EFB45 floor box footprint. Confirm your floor box model before ordering — this insert is dimensioned for the EFB45 series, and a mismatched cover defeats the flush-fit purpose entirely.
• Standard receptacle type: Accommodates standard receptacle configurations, giving you flexibility to populate the box with the power and data modules your project requires rather than being locked into a proprietary interface.
• Black finish: The black colorway integrates cleanly with dark raised floor tiles common in data center and broadcast environments. Avoids the visual noise of mismatched hardware in finished installations.
• Designed for raised floor infrastructure: Built specifically for the raised floor box environment — not a surface-mount workaround. Proper fit means the cover engages the box correctly, maintaining the structural integrity of the floor surface above.
• TAA status — not compliant: The EFB45CTBK is not TAA compliant. If your project is a federal government installation or requires GSA Schedule compliance, you'll need to verify an alternative part number in the Middle Atlantic EVO line that carries TAA designation before specifying this cover.

Integration & Compatibility

The EFB45CTBK is engineered for the Middle Atlantic EVO Series EFB45 raised floor box platform. Compatibility is specific — this cover insert is not a universal fit for other floor box families or competing brands. Verify the base unit model number against Middle Atlantic's EFB45 series before including this part in a bill of materials.

For AV and security rack infrastructure that pairs with floor box deployments, see AV rack accessories and cable management components that complete the installation from the floor to the rack. If you're planning power distribution alongside this floor box installation, power distribution units from the same product line can simplify procurement.

The standard receptacle opening supports common power and data insert modules — coordinate with your AV designer or systems integrator to confirm module compatibility before the installation date, since field-sourcing inserts after the floor is closed is an avoidable delay.

Frequently Asked Questions

Q: Is the EFB45CTBK TAA compliant for government projects?

A: No. The EFB45CTBK is not TAA compliant. Federal installations or projects requiring GSA Schedule compliance should verify an alternative TAA-designated part number in the Middle Atlantic EVO Series before specifying this cover insert.

Q: What floor box does the EFB45CTBK cover fit?

A: The EFB45CTBK is designed for the Middle Atlantic EVO Series EFB45 raised floor box. It is not a universal cover — confirm your base unit is an EFB45 series model before ordering.

Q: What are the physical dimensions of the EFB45CTBK?

A: The cover insert measures 9.94 inches (25.2 cm) wide and 1.19 inches (3 cm) in height above the floor plane.

Q: What color is the EFB45CTBK?

A: Black.

Q: What receptacle type does the EFB45CTBK support?

A: Standard receptacle type, which accommodates common power and data insert modules for the EFB45 floor box platform.

The detail that trips up most AV and security integrators on the EFB45CTBK is the TAA status — it's explicitly non-compliant, and that single line item will block a federal procurement if it gets missed until submittal review. For commercial work, it's a non-issue, but flag it early on any government-adjacent project. The 1.19-inch flush profile is genuinely low, which is the right call for any space where rolling equipment or foot traffic crosses the box location regularly.

Technical Highlights:

• 1.19 in flush height: At 3 cm above floor plane, this cover presents minimal trip risk in active environments — a real consideration in broadcast control rooms and trading floors where people move fast and floor boxes are in the middle of the action.
• 9.94 in width precision fit: Sized specifically for the EFB45 footprint at 25.2 cm. There's no adjustment range — either it matches your base unit or it doesn't. Verify the base model number before it ships.
• Standard receptacle opening: Keeps your insert module options open rather than locking you into a proprietary module ecosystem. Coordinate module selection with the AV designer before the floor goes down.

Deployment Considerations:

• Confirm the base unit is specifically an EFB45 series floor box — this cover is dimensioned for that platform only, and a wrong-family fit will leave gaps or prevent proper seating.
• TAA non-compliance (confirmed in the product specification) is a hard blocker for federal and many state government installations — do not spec the EFB45CTBK on those jobs without verifying an alternative Middle Atlantic part number first.

Best fit: corporate AV buildouts, broadcast and production control rooms, and enterprise conference centers on raised floor systems where a finished, low-profile cable access point matters and federal procurement rules don't apply.
