Southwire 24151-1/2-UPC Old Work Octagon Box 3.5x3.5 in

Product Description

The SOUTHWIRE 24151-1/2-UPC is a steel old-work octagon box designed for mounting ceiling and wall lighting fixtures, ceiling fans, and convenience outlets in retrofit electrical installations. Built from durable steel with a combo-head fixture mounting design, this box installs into existing walls or ceilings without requiring access from behind the surface. The included cover mounting screws allow direct attachment of fixture canopies and cover plates. At 3.5 inches by 3.5 inches, this octagon box fits standard circular fixture footprints and is sold individually.

This box is suited for residential and light commercial retrofit wiring projects where ceiling or wall openings already exist. Electricians use old-work boxes when adding or replacing light fixtures, exhaust fans, or convenience outlets in finished spaces. The octagon profile accommodates standard round canopy fixtures and ceiling fan mounting brackets. It is a common solution in renovation work where new-construction boxes are not accessible.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements for outlet box fill and support. De-energize the circuit at the breaker panel and verify absence of voltage with a meter before handling wiring.
