Southwire 54C1-UPC 4 Inch Round Blank Box Cover

Product Description

The SOUTHWIRE 54C1-UPC is a flat blank cover designed to close off a 4-inch octagon electrical box. It serves three common purposes: sealing a junction box, providing a surface to mount a wiring device, or supporting a light fixture. Keyhole mounting holes allow for straightforward alignment and attachment without special tools. The cover is UL listed and RoHS compliant, meeting standard safety and environmental requirements for electrical installations. Licensed electricians and maintenance technicians use this cover in both new construction and retrofit applications where a finished, code-compliant termination is needed at an octagon box location.

This cover is suited for residential and light commercial electrical work wherever a 4-inch octagon box needs to be closed off or transitioned. Common scenarios include terminating unused junction boxes in ceilings or walls, covering boxes that are roughed in but not yet fitted with a device, or providing a mounting base for a ceiling-mounted light fixture. Its gray finish blends with standard electrical box installations.
