The IPEX OB15/10 is a 4" PVC octagon box built for professional electricians and contractors who need a reliable, code-compliant solution for residential and light commercial wiring projects. Lightweight and corrosion-resistant, this box handles damp-location installations with ease — whether you're roughing in ceiling fixtures, junction points, or outlet connections on the job site. Each box ships complete with a cover, gasket, four reducing bushings (3/4" × 1/2"), and four sealing caps for unused entry hubs, so your crew arrives ready to work without hunting for hardware.
