Southwire 72C1-UPC Square Flat Blank Cover 4-11/16 in

Product Description

The SOUTHWIRE 72C1-UPC is a flat blank cover plate designed for use with 4-11/16 inch square electrical boxes. It closes off the box face where no device, switch, or receptacle is being installed, providing a clean and code-compliant termination point. The cover is fabricated from zinc-plated steel, giving it solid corrosion resistance for both new construction and retrofit applications. A standout feature is the angled slots built into the cover face, which allow up to 1/2 inch of box misalignment compensation on upright framing members — reducing rework time during rough-in. Licensed electricians and electrical contractors are the primary installers of this component.

This blank cover is suited for residential and light commercial electrical installations where a 4-11/16 inch square box is used and the opening requires a finished, secure closure. Typical scenarios include junction box covers in utility spaces, unfinished basements, mechanical rooms, and above-ceiling applications where a device is not required but the box must remain accessible and properly covered per NEC requirements.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit and verify the absence of voltage at the box before handling any cover or wiring. Secure the cover using the appropriate machine screws for the box — do not overtighten, as this can distort the plate. Verify local jurisdiction requirements for blank cover use on accessible junction boxes.
