Middle Atlantic EVO Furn Feed BX ON Grade - EFBFF-OG

Middle Atlantic EFBFF-OG EVO Furniture Feed Floor Box — On Grade

Overview

The Middle Atlantic EFBFF-OG is an on-grade furniture feed floor box from the Evolution Series, designed to route power and low-voltage cabling cleanly through raised or on-grade floor environments. At 6.63 in wide, 4.25 in tall, and 7.25 in deep, the EFBFF-OG fits within standard furniture base cutouts where a flush, finished appearance matters — open-plan offices, boardrooms, and command centers where exposed cable runs are not acceptable. TAA compliance makes it a straightforward procurement choice for federal, state, and education contracts subject to the Trade Agreements Act.

Key Features

• On-Grade Installation: Designed specifically for on-grade floors (not raised-access tile), so you get a stable, permanent mount without the height adapters or leveling hardware that raised-floor variants require. Specify this model when your floor is concrete slab or standard subfloor construction.
• Compact Footprint (6.63 in × 4.25 in × 7.25 in deep): The shallow 4.25 in profile keeps the box under most furniture bases and within typical slab chase depths — confirm your floor core depth before ordering, as 7.25 in is the full box depth requirement below finished floor surface.
• TAA Compliant: Procurement officers on GSA schedules, DoD contracts, or state IT contracts can specify the EFBFF-OG (often searched as EFBFF OG) without a TAA waiver. Verify your contract vehicle's country-of-origin requirements, but TAA compliance satisfies most domestic-preference clauses for AV and low-voltage infrastructure.
• Evolution Series Platform: Part of Middle Atlantic's Middle Atlantic AV and infrastructure Evolution Series, which uses a consistent modular insert system — power modules, data inserts, and connectivity plates from the same family drop in without custom machining.

Integration & Compatibility

The EFBFF-OG is designed for structured cabling and low-voltage floor infrastructure deployments where furniture feed points need a finished, code-compliant termination. It pairs with Middle Atlantic Evolution Series inserts for power and data. Consult Middle Atlantic's insert compatibility matrix to confirm which modules fit the EFBFF-OG body before ordering inserts separately — the box and inserts are typically sold independently.

For AV integration projects requiring rack and enclosure accessories, the Evolution Series floor box ecosystem coordinates with Middle Atlantic's broader furniture and credenza product line. If your project includes a raised-floor environment rather than on-grade, Middle Atlantic offers raised-floor variants in the same series — the EFBFF-OG is not the correct model for tile-access raised floors.

Frequently Asked Questions

Q: Is the EFBFF-OG TAA compliant?

A: Yes. The EFBFF-OG carries TAA compliance, making it suitable for federal, state, and education procurement contracts subject to Trade Agreements Act requirements.

Q: What is the difference between on-grade and raised-floor variants in this series?

A: On-grade models like the EFBFF-OG are engineered for installation in concrete slab or standard subfloor construction. Raised-floor variants in the Evolution Series are designed for tile-access raised floor environments and use different mounting hardware. Ordering the wrong grade type will create installation problems — confirm your floor type before purchasing.

Q: What are the dimensions of the EFBFF-OG?

A: Width 6.63 in (16.8 cm), height 4.25 in (10.8 cm), depth 7.25 in (18.4 cm). Confirm your floor cutout and chase depth accommodates the full 7.25 in box depth before specifying.

Q: Does the EFBFF-OG include power or data inserts?

A: Based on available product evidence, the EFBFF-OG box body and inserts are sold separately. Consult Middle Atlantic's Evolution Series insert compatibility documentation to select appropriate power and data modules for your application.

Q: Can the EFBFF-OG be used in a raised-access tile floor?

A: No. The EFBFF-OG is rated for on-grade installation only. Raised-floor environments require the appropriate raised-floor variant from the Evolution Series.

Eden Phillips

The spec that matters most when specifying the EFBFF-OG is the 7.25 in depth — that is your minimum floor chase clearance requirement. I have seen projects stall at rough-in because the integrator ordered the box before confirming slab chase depth with the GC. On a 4-inch slab with no chase, this unit does not fit. Get that measurement in writing before the EFBFF-OG goes on a purchase order.

Technical Highlights:

• On-Grade Grade Type: Distinct from raised-floor variants — the mounting geometry and base seal are specific to poured or standard subfloor surfaces, not tile-access floors. Wrong grade type = a return shipment and a delayed rough-in.
• 6.63 in × 4.25 in footprint: Fits within most standard furniture base cutout templates in the Evolution Series. Verify against your furniture vendor's cutout spec — non-standard furniture may require a custom cutout.
• TAA Compliance: Pre-qualified for GSA and most federal/SLED contracts. Eliminates the TAA waiver paperwork that delays procurement on government AV buildouts.

Deployment Considerations:

• The EFBFF-OG ships as the box body — inserts for power and data are ordered separately from Middle Atlantic's Evolution Series insert catalog. Budget and lead time for inserts independently; they are not included.
• At 4.25 in height, this unit is shallower than some competitive floor boxes, which helps in low-profile furniture installs — but it also limits the insert module count you can stack. Plan your insert layout before finalizing the order.

Best fit: government facility AV buildouts, federal command centers, and SLED conference room infrastructure where TAA compliance is a hard procurement requirement and on-grade concrete or standard subfloor construction is confirmed.
