Middle Atlantic EVO 10GNG Flrbx ON Grade - EFB6S-OG

Middle Atlantic EFB6S-OG Evolution Series On-Grade Raised Floor Box

Overview

The Middle Atlantic EFB6S-OG is an on-grade raised floor box from the Evolution Series, engineered for structured cabling and AV/security infrastructure deployments where power, data, and connectivity need to surface cleanly at floor level. At 16.13 inches deep, 13.75 inches wide, and 4.13 inches tall, this unit is sized for installations where access-floor tile cutouts must accommodate a full complement of modules without crowding adjacent tile supports. The EFB6S-OG (often searched as EFB6S OG) carries TAA compliance, making it a valid line-item for federal procurement, GSA schedules, and government-adjacent projects where Trade Agreements Act sourcing is a contract requirement.

On-grade floor boxes differ from recessed or low-profile variants in one critical way: the box sits at finished-floor level rather than below it, which suits installations on concrete slab, raised access flooring, or anywhere a flush-to-grade surface is the design target. If your floor plan calls for a below-grade or recessed profile, a different grade type is the correct selection — the EFB6S-OG is specifically the on-grade variant in this family.

For integrators specifying Middle Atlantic infrastructure solutions across enterprise AV, command centers, or security operations centers, the Evolution Series floor box line offers a consistent modular platform. Pair this floor box with compatible floor box accessories and modules to populate the box with the specific power, data, and AV connection types your project requires. When planning cable pathways alongside this unit, cross-reference your structured cabling and pathway selections to confirm conduit entry compatibility.

Key Features

• On-Grade Installation: Designed to sit flush with finished floor surfaces — concrete slab or raised-access flooring — so there is no raised lip to create a tripping hazard or interfere with furniture placement in open-plan environments.
• TAA Compliance: Sourced and manufactured in compliance with the Trade Agreements Act, clearing the primary procurement gate for federal contracts, DoD facilities, and state/local projects with TAA requirements written into specs.
• 16.13-Inch Depth: The 41 cm interior depth provides meaningful vertical clearance for cable management, module stacking, and conduit connections below the floor surface without requiring an oversized cutout.
• 13.75-Inch Width: At 34.9 cm wide, the box accommodates side-by-side module configurations — useful when a single floor location needs to serve both power and data simultaneously.
• 4.13-Inch Profile Height: The 10.5 cm above-floor height keeps the box low-profile enough for most security operations center and command-room floor plans where furniture clearance is tight.

Integration & Compatibility

The EFB6S-OG is part of Middle Atlantic's modular Evolution Series floor box platform. Module inserts — power, data, HDMI, USB, and combination plates — are specified separately and snap into the box frame. Confirm module compatibility against the Evolution Series configurator before finalizing your bill of materials. AV rack and infrastructure planning resources can help align floor box placement with rack layout and cable run distances.

Frequently Asked Questions

Q: Is the Middle Atlantic EFB6S-OG TAA compliant?

A: Yes. The EFB6S-OG carries TAA (Trade Agreements Act) compliance, qualifying it for federal, DoD, and government-contract procurement where TAA sourcing is required.

Q: What does "on-grade" mean for the EFB6S-OG?

A: On-grade means the floor box is designed to install flush with the finished floor surface — concrete slab or raised-access floor tile — rather than recessed below grade. If your project requires a below-grade or recessed profile, a different grade-type variant in the Evolution Series is the correct selection.

Q: What are the dimensions of the EFB6S-OG?

A: The EFB6S-OG measures 16.13 inches deep (41 cm), 13.75 inches wide (34.9 cm), and 4.13 inches tall (10.5 cm).

Q: Does the EFB6S-OG come with modules, or are they sold separately?

A: Based on the product design of the Evolution Series platform, the floor box frame and module inserts are specified independently. Confirm exact package contents and compatible modules against the Middle Atlantic Evolution Series configurator or your distributor's bill of materials before ordering.

Q: Is the EFB6S-OG suitable for raised-access flooring environments?

A: Yes. The on-grade design and 16.13-inch depth make it well-suited for raised-access floor installations in data centers, security operations centers, and command rooms where cable management below the floor tile is part of the infrastructure design.

When I spec floor boxes for security operations centers and command rooms, the first question is always grade type — and the EFB6S-OG settles that immediately with its on-grade designation. At 16.13 inches of usable depth, this box gives you real room to manage conduit entries and cable slack below the tile surface, which is the difference between a clean install and a box crammed so tight you cannot pull a replacement cable without cutting something.

Technical Highlights:

• TAA Compliance: The EFB6S-OG meets Trade Agreements Act requirements out of the box — no country-of-origin variance process needed for federal or DoD facility integrations, which typically adds weeks to a bid cycle if overlooked at spec time.
• 16.13-Inch Depth: 41 cm of vertical interior clearance is generous by floor box standards — enough to run a conduit stub, loop service slack, and still seat modules without forcing cables against the lid frame.
• 13.75-Inch Width: The 34.9 cm footprint supports side-by-side power and data module rows in a single floor penetration, which reduces the number of cutouts required in a high-density seating or console layout.

Deployment Considerations:

• Confirm tile cutout dimensions against the 13.75 W x 16.13 D footprint before ordering — raised-access floor tile vendors have varied standard cutout sizes, and a field modification to a structural tile is a change-order you want to avoid.
• The EFB6S-OG is the on-grade variant specifically; if your architectural drawings call for a flush-recessed or below-grade installation, verify the grade type of the variant you select — the Evolution Series includes multiple grade options and mixing them on a single floor plan creates a visible height inconsistency.

This box is the right call for new-build security operations centers and enterprise command rooms on raised-access flooring where TAA compliance is a contract line item and cable management depth actually matters at the console positions.
