Middle Atlantic RFB6E Above-Grade Concrete Gang Floor Box
Overview
The Middle Atlantic RFB6E is a gang-configuration above-grade floor box designed for concrete slab installations where AV, power, and low-voltage connections need to surface cleanly at floor level. The RFB6E fits structured integration environments — conference rooms, auditoriums, open-plan commercial spaces — where recessed floor access points must sit flush or slightly above a finished concrete surface without a sub-floor cavity. This is not a suspended-ceiling or below-grade application; if your slab is poured and finished, the above-grade form factor eliminates the need for pre-pour rough-in.
Compatibility
The RFB6E is part of Middle Atlantic's RFB floor box series, designed to accept standard gang inserts for power, data, and AV connectivity modules. Compatible inserts and cover plates are sourced from the Middle Atlantic RFB accessory line — confirm insert count and module configuration against the gang count of this specific box before ordering. Intended for use within AV infrastructure and rack and enclosure systems where floor-level distribution complements overhead or wall-mounted equipment. Consult the power and AV accessories category for compatible modules and cover configurations.
Installation Notes
Above-grade installation means the box body sits on top of the concrete surface — no core drill or pre-pour embed required, making it suitable for retrofit projects on finished slabs. Secure anchoring to the concrete surface is required to prevent movement under repeated use; verify anchor hardware compatibility with your slab composition. Route conduit or low-voltage cabling to the box per local electrical code. Above-grade placement does introduce a slight floor-level protrusion — factor this into ADA compliance review and furniture layout for the space.
