Southwire 54151-CFBH Galvanized Steel Ceiling Fan Junction Box, 4 Knockout

The Southwire 54151-CFBH is a galvanized steel ceiling fan junction box engineered for secure mounting of lighting fixtures and fan assemblies in new-construction and renovation projects. Its round profile fits neatly into standard ceiling joist layouts and wall cavities, while the robust steel construction delivers the durability and corrosion resistance needed for demanding electrical installations. The box provides a reliable, code-compliant anchor point that reduces vibration and wobble in ceiling-mounted fixtures.

This junction box streamlines the installation process with pre-punched knockouts that eliminate the need for manual drilling, allowing electricians to quickly route conduit and cable without additional adjustments. The unobstructed internal conduit pathway keeps wiring runs straight and accessible, helping installers meet electrical code requirements faster while improving overall safety and ease of use.
