UL and CSA listed with a NEMA 3R rating, it’s designed for secure, compliant installations in wet or dry environments, complete with all necessary mounting hardware. ## Description Sigma's weatherproof one-gang boxes provide a junction for conduits and can house a single wired device such as a receptacle or switch.

Review: Very thick durable metal and mounting was easy. I had made a custom lamp and this box had the stability I was looking for. I’m not using it in a water located area but with the seals included, appears it would do well.
