Included hardware and a pre-installed ground screw ensure secure, code-compliant installation. ## Description Sigma Engineered Solutions weatherproof one-gang junction box provides a place for conduit, receptacle or switch that is single-wired. The rugged, die-cast construction prevents moisture penetration making the box suitable for wet, damp or dry locations.

Product is UL and CSA listed. Review: Solid build, great value for an exterior box - Great value on this one. Sturdy metal construction will protect the outlet, well built, and mounting was straightforward. Knockouts give you flexibility on which side you want to run conduit through. One thing to plan for if you're mounting on stucco like i did, the box doesnt sit flush against the uneven surface. I ran a bead of exterior polyurethane sealant around the perimeter once it was mounted to keep water from working its way behind it. Wall texture issue, not a product issue, but worth knowing before you start. Otherwise, the box itself water resistant as designed. Hard to beat for the price.
