Middle Atlantic 8-GANG Floor BOX Steel FC - EFB8S-FC

Middle Atlantic EFB8S-FC 8-Gang Fire-Classified Steel Floor Box

Overview

The EFB8S-FC is Middle Atlantic's Evolution Series 8-gang, fire-classified steel floor box designed for structured AV and technology installations where floor-access connectivity must meet fire-code requirements. At 19.29" wide x 14.63" high x 24.79" deep (49 cm x 37.2 cm x 63 cm), this is a deep-well box built to accommodate the wiring bulk and bend radius demands of multi-cable runs serving conference rooms, boardrooms, classrooms, and open-plan commercial spaces. TAA compliance makes it a straightforward fit for government facilities and federally funded projects with domestic sourcing requirements. The EFB8S-FC belongs to Middle Atlantic's Middle Atlantic floor box and AV infrastructure line, which covers modular, scalable in-floor connectivity solutions for commercial integrators.

Compatibility

The EFB8S-FC is part of the Evolution Series fire-classified floor box family from Middle Atlantic (Legrand AV). It is designed to accept Evolution Series inserts and modules — cover plates, power modules, data keystones, and multimedia interface plates that snap into the 8-gang opening. Verify insert compatibility against the Evolution Series configurator on the manufacturer's site before specifying, as gang count and box depth determine which insert combinations fit without forcing cable bends. This box is suited to installations using floor box and floor stand systems in commercial AV rack and cable management projects. If your project requires more capacity, consider the 10-gang variant (EFB10S-FC) in the same Evolution Series. For AV rack and cable management accessories, the broader Middle Atlantic product family covers complementary infrastructure components.

Installation Notes

The 24.79" depth requires adequate sub-floor clearance — confirm floor void depth before ordering, particularly in slab-on-grade or shallow plenum applications where 63 cm of vertical clearance may not be available. Steel construction and fire-classified rating mean this box is intended for installations governed by applicable fire codes; coordinate with the AHJ (Authority Having Jurisdiction) on rough-in requirements. TAA-compliant sourcing is verified for this SKU — suitable for government and public-sector AV projects without additional country-of-origin documentation burden.
