Southwire 52C3-5/8-UPC 4x4 Square Raised Cover Fixture Ring

Product Description

The SOUTHWIRE 52C3-5/8-UPC is a round fixture ring designed to convert a 4-inch by 4-inch square electrical box into a 3-1/2-inch round opening for mounting light fixtures in walls and ceilings. The ring features 8-32 threaded mounting tabs that support direct fixture attachment during lighting retrofit work. Angled slots on the cover compensate for up to 1/2 inch of box misalignment on upright framing members, reducing the need for repositioning during rough-in corrections. The cover is UL listed and RoHS compliant, meeting standard requirements for residential and light commercial electrical installations. Licensed electricians and experienced DIYers working on fixture upgrades or box conversions will find this ring straightforward to install with common hand tools.

This fixture ring is suited for retrofit and new-construction lighting applications where a standard 4-inch square box needs to be adapted for a round-opening fixture mount. Typical scenarios include ceiling fixture replacements, wall sconce installs, and lighting upgrades where the existing box is a 4-inch square style. The 2-3/4-inch on-center hole spacing and raised profile accommodate standard fixture canopies without additional adapters.

Always shut off circuit power at the breaker panel and verify the circuit is de-energized before beginning work.
