The Round Fixture Box Ring is used to mount light fixtures in walls and ceilings. The rings convert a 4 in. square box to a round opening with 8-32 threaded mounting tabs for lighting retrofit applications. Angled slots on the covers compensate for up to 12° of box misalignment on upright framing members. Additionally, the rings are UL and RoHS compliant.
