Middle Atlantic RFB119-SSR1 Single-Gang Receptacle Device Plate
Overview
The RFB119-SSR1 is a single-gang receptacle device plate from Middle Atlantic's Middle Atlantic floor box line, designed to provide a finished, single-receptacle opening in concrete floor box installations. The RFB119-SSR1 features a 1.39 in (35.3 mm) opening diameter — sized to accept a standard single receptacle device, giving installers a clean termination point for power access in raised-floor AV, security, or IT infrastructure deployments. TAA compliant, making it eligible for government and federally funded projects that require products meeting Trade Agreements Act sourcing requirements.
Compatibility
This device plate is designed for use with Middle Atlantic's RFB9 and RFB11 series concrete floor boxes. Confirm the specific floor box model and gang count before ordering — the RFB119-SSR1 is a single-gang configuration and must match the corresponding bay in the floor box assembly. It is not interchangeable with multi-gang configurations or floor box series outside the RFB9/RFB11 family.
Installation Notes
The 1.39 in (35.3 mm) opening accommodates a standard single receptacle. Verify receptacle device dimensions against the opening before finalizing the install — oversized devices will not seat correctly. Designed for concrete floor installations where the floor box is set flush; confirm the floor box is level and set to final floor height before installing the device plate to avoid misalignment. For power distribution planning in multi-outlet floor box layouts, confirm the full assembly configuration against the RFB9/RFB11 series documentation to ensure correct plate and device pairing.
