Southwire MSBFAN New Work Fan/Fixture Ceiling Box, 24Cu-In

The Southwire MSBFAN New Work Fan/Fixture Ceiling Box is a heavy-duty ceiling electrical box designed to provide secure support for ceiling fans and light fixtures in both new construction and retrofit applications. Built with extra-thick polycarbonate walls and reinforced steel hardware, this box delivers the strength and rigidity needed for moving loads like paddle fans. With a 24 cubic inch capacity and extra-deep design, it also offers plenty of room for wiring, detectors, and fan components—because crowded electrical boxes never make installation easier.
