Middle Atlantic EVO Furniture Feed BX - EFBFF

Middle Atlantic EFBFF Evolution Series Furniture Feed Floor Box

The Middle Atlantic EFBFF is an above-grade furniture feed floor box from the Evolution Series, designed to route low-voltage cabling cleanly through raised access floors in commercial AV, security control rooms, and systems integration environments. At 6.63 in wide, 4.25 in tall, and 7.25 in deep, the EFBFF fits within standard raised-floor grid cutouts while keeping cable egress organized and presentable at workstation and equipment furniture bases.

Key Features

• Above-Grade Configuration: Rated for above-grade raised floor installations — the box mounts flush or proud of the floor surface, making it the right pick for accessible raised-floor environments rather than in-slab or below-grade pours. Confirms correct application before you order.
• Compact Footprint (6.63 × 4.25 × 7.25 in): The profile fits standard raised-floor tile cutouts without requiring custom modification. The 7.25 in depth provides sufficient plenum clearance for cable bend radius compliance on Cat6A, fiber, and low-voltage runs.
• TAA Compliant: Meets Trade Agreements Act requirements — eligible for U.S. federal, state, and municipal procurement contracts where TAA compliance is mandatory. Verify your project's specific compliance requirements with your contracting officer, but the EFBFF clears the TAA bar.

Integration & Compatibility

The EFBFF is designed to work within Middle Atlantic's Evolution Series floor box ecosystem. It is suited for cable management in raised-floor control rooms, command centers, security operations centers, and open-plan office environments where clean cable routing from floor to furniture is required. Pair with compatible floor box inserts and covers from the Evolution Series for a complete installation. Consult your raised floor solutions plan to confirm tile cutout dimensions and plenum depth before installation.

The EFBFF's above-grade rating is the detail that matters most at the quoting stage — specify it for raised-access-floor environments only. I've seen integrators order the wrong grade and end up with a box that either protrudes incorrectly or doesn't interface cleanly with the tile surround. The 7.25 in depth is also worth checking against your plenum clearance before the floor tiles go down.

Technical Highlights:

• TAA Compliance: The EFBFF meets Trade Agreements Act requirements — a hard procurement gate on federal and GSA-schedule projects that is easy to overlook until contract award.
• Compact Form (6.63 × 4.25 × 7.25 in): The depth dimension (7.25 in / 18.4 cm) is the critical fit check against your raised-floor plenum height — confirm clearance before cutting tile.
• Above-Grade Design: Purpose-built for surface-accessible raised floors; not rated for below-grade or poured-in-place concrete applications.

Deployment Considerations:

• Verify your raised-floor tile cutout dimensions match the EFBFF footprint (6.63 × 4.25 in opening) before installation — Evolution Series accessories are designed as a matched system.
• The EFBFF is the feed box only; inserts, covers, and modular faceplates are separate Evolution Series components — confirm the full bill of materials before ordering.

Best suited for security operations centers, AV control rooms, and commercial open-plan environments on raised-access flooring where TAA compliance is a contract requirement and clean below-furniture cable egress is the design goal.
