Perfect!
Exactly what I needed, very well made and plenty of sturdy protection. Clean look too, and mounting is easy.

Good as always.
Sigma engineered parts are exactly what they say they are. Made from good materials, and reasonably heavy duty. This outdoor single-gang box is painted white. The paint is tough and survives some handling. After installation, it does seem weather proof, but only time will tell. Had to add silicone sealant to each of the plugs to ensure weatherproofing. Will buy again.

Great value, superb bargin
I couldn't be happier with these electrical boxes. They are cheaper than other outlet boxes by almost 1/2. They have a nice appearance and come complete with all of the necessary hardware. I've purchased 3 of these boxes so far. I intend to buy more for the inside of my home as well. Highly recommended for its value and construction.

Knock-outs in the back permit flush mounting.
The previous owner wired a florescent lamp directly from a wire exiting the ceiling in my bathroom, then build an attractive box to enclose it. When the ballast went bad, I decided to replace the florescent fixture with an LED fixture. The new fixture was shorter than the old one and had its own AC cord, so I needed to add a junction box to connect the two sets of wires together. The space was narrow, so I used this rectangular box. I was pleasantly surprised to find two offset "knockouts" for screw holes in the back so I could mount this to the ceiling. (I say "knockouts", but I had to drill them out.) The waterproof lid (sold separately) completed the assembly and it is fully functional and attractive.
