Southwire 54171-FANOW-UPC 4 in Bracket Mount Ceiling Fan Box

Product Description

The SOUTHWIRE 54171-FANOW-UPC is a bracket mount retrofit ceiling fan box designed for new or existing ceiling installations where a standard stud mount is not available. The box uses an expandable bracket that spans between joists, allowing secure mounting without direct stud access. It ships with combination-head cover mounting screws included. UL and RoHS listings confirm it meets safety and environmental standards required by most local codes. Electricians and qualified installers use this box when retrofitting fan-rated support into finished ceilings without opening drywall beyond the box cutout.

This ceiling fan box is suited for residential and light commercial applications. It supports the installation of ceiling fans, ceiling and wall lighting fixtures, and convenience outlets or devices. The retrofit design makes it a practical choice for remodel and renovation work where joist access is limited or the existing box is not fan-rated. The 4-inch round box format is a standard size used across a wide range of fan and fixture applications.
