Middle Atlantic RFB119-B 1-Gang Blank Device Plate

Overview

The Middle Atlantic RFB119-B is a single-gang blank device plate designed to cover unused openings in Middle Atlantic RFB9 and RFB11 series concrete floor boxes. When a floor box position doesn't require a connector or outlet, leaving it open invites debris, trip hazards, and code compliance issues — the RFB119-B closes that gap cleanly with a flush, finished surface. It's the correct fill piece for any floor box accessory install where one or more device slots are not immediately populated. TAA compliance makes it suitable for government facilities, federal installations, and GSA-schedule projects where country-of-origin restrictions apply.

Compatibility

The RFB119-B is compatible with Middle Atlantic RFB9 and RFB11 series concrete floor boxes. It occupies one standard device gang position within those enclosures. Do not attempt to fit this plate to non-Middle Atlantic floor boxes or single-gang wall-plate applications — the mounting geometry is specific to the RFB series frame. If your floor box has multiple open positions, order one RFB119-B per unfilled gang slot.
