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.

Electrical box
Just like other electrical boxes they work just fine and are excellent quality. Only complaint is the screw covers that come with it are plastic and not metal.

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.

Le même article vaut bien plus cher en quincaillerie et la qualité n’est pas aussi bonne ! Très satisfait de cet achat !

Nicely finished so that it is not unpleasant to the eye when it is not buried underneath drywall.
