Middle Atlantic 6 Gang ON Grade Concrete - RFB6E-OG

Middle Atlantic RFB6E-OG 6-Gang On-Grade Concrete Floor Box

Overview

The Middle Atlantic RFB6E-OG is a 6-gang floor box engineered for on-grade (slab-level) concrete installations — the deployment scenario where conduit and outlet infrastructure must be cast into or surface-mounted on a concrete floor rather than raised in a sub-floor cavity. Designed for AV, security, and structured wiring environments, the RFB6E-OG provides six discrete gang positions, giving installers the capacity to terminate power, low-voltage data, HDMI, or control wiring at a single floor location without running multiple separate surface-mount boxes. This makes it a practical fit for boardrooms, classrooms, lobbies, and open-plan security operations centers where floor-fed cable management is required and wall routing is not an option.

Compatibility

The RFB6E-OG is part of Middle Atlantic's RFB (Recessed Floor Box) series, designed for use with standard single-gang and multi-gang insert plates sized to the RFB footprint. It is intended for use with Middle Atlantic's range of floor box covers and inserts from the same RFB product family. Compatible inserts typically accept keystone-style low-voltage modules, Decora-format AC outlets, and blank gang fillers — confirm insert compatibility against the specific Middle Atlantic RFB series insert lineup before ordering. When planning a full structured wiring system, pair the RFB6E-OG with appropriately rated conduit fittings rated for concrete-encased or surface conduit applications. Verify local electrical code compliance for on-grade concrete floor box installations, as requirements for cover-plate flush tolerance and conduit entry knockout sizing vary by jurisdiction.
