Review: Waterproof and the right color... - This outdoor metal box was perfect for running power around my outdoor patio and cabana. It matched the wood well. There are several selctions for the knockout size and location that made running the conduit a snap. The build quality and color are on point. They are easy to install with the tabs included and a good value for the money. I couldn't find this color/configuration at my local big box or Ace Hardware.
Review: Just What Was Needed - Used these to replace some older ones in my backyard. They worked out great. Easy to use and I would definitely use them again. You can't find these kind at the big box stores!

### ⭐⭐⭐⭐⭐ Bronze Color blended nicely into wood
*by J***S on January 24, 2020*

[Sigma Electric, Bronze 14251-5XBR 1/2-Inch 5 Hole 1-Gang Side Entry Box ] Just a basic, all metal 1 Gang Box in Bronze used for installing an electrical outlet. It included bronze plugs for the access holes not used. I wanted something that was close to the dark stain used on the porch ceiling since the box would have to be surface mounted (and not recessed into the wall). I combined mine with an expandable low profile cover (seen on top in the picture), and mounted them both into my porch ceiling so that I could leave my low voltage, outdoor decorative lights plugged in without exposing the outlet to any direct moisture.
