Need a sturdy metal electrical box for a ceiling light, fan, or junction? This 4-inch octagon (or round) box is built for the job. It features 1/2-inch knockouts (KOs) on multiple sides, giving you flexibility for running conduit or cable into the box. It's similar to popular models like the Raco 153. The box is unbranded/generic but new and made of durable steel. Perfect for DIY electrical projects, renovations, or repairs where you need a reliable enclosure for wiring connections. Use it for light fixtures, smoke detectors, or as a pull box. Installation requires securing it to a joist or using a bracket. Always follow local electrical codes. A basic, essential component for any electrician or handy homeowner's supplies.
