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

Product Description

The SOUTHWIRE 52C3-UPC is a round fixture ring designed to mount light fixtures in walls and ceilings. It converts a 4-inch square electrical box to a 3-1/2-inch round opening, making it a practical solution for lighting retrofit work. The cover includes 8-32 threaded mounting tabs that accept standard fixture hardware. Angled slots built into the cover compensate for up to 1/2 inch of box misalignment on upright framing members, reducing rework during rough-in and finish stages. Licensed electricians and lighting contractors install this cover as part of residential and light commercial fixture installations. The 52C3-UPC carries UL listing and RoHS compliance.

This fixture ring is suited for residential and light commercial applications where a 4-inch square box needs to be transitioned to a round fixture opening. It is commonly used during lighting retrofits when replacing or upgrading ceiling or wall-mounted light fixtures. The on-center spacing of 2-3/4 inches aligns with standard fixture mounting patterns. The design accommodates minor box misalignment, which is especially useful when working with existing framing that may not be perfectly plumb.
