What Customers Are Saying

Customers overwhelmingly praise this electrical box for its secure screw-to-stud mounting system, which eliminates drywall pull-through risks and provides unmatched stability compared to traditional nail-on alternatives. Installation is consistently described as intuitive and straightforward, with an adjustable depth gauge enabling precise positioning. Reviewers highlight the heavy-duty PVC construction, deep interior accommodating multiple wires, and ability to convert single-gang openings without major wall disruption—particularly valuable for retrofitting and remodeling. A few mention minor issues like screw stripping or slight wobbliness, but these rare concerns are vastly outweighed by overall satisfaction. Most customers declare it the most reliable old-work box available.

Sturdy, easy to install.

Would Recommend

This is a high quality, sturdy 2-gang old work box that mounts well against a stud and is easy to install. Trace the outside, cut it in the drywall, then use the interior-mounted screws to install. Go to choice for adding junction boxes next to studs.

Solid gang box new/old construction.

Looks of features

Would Recommend

These are so much better than the single gang old work boxes. Finally a product that is secure to a stud but you don’t have to cut the wall open to get a double gang.

10 times better than cheap old work boxes

Would Recommend

super secure and depth adjustable. I use to use the flappy eared boxes but these are well worth the extra cost.. one thing I did notice was as the screws pull in it sets the box slightly deeper than held position. So recommend holding box out a 1/16 -1/8 in. practice to dial in

Used to replace smaller box in ceiling

Would Recommend

I used this 2 gang box to replace a smaller electrical box in the ceiling that is holding up a light. I was having a very loud squeak in the ceiling from the person walking around above. I lucked out and it was around where the light is. I used wood shims to stick in and fill gaps between the top of the joists and bottom of the subfloor above and it actually worked. I needed the hole larger to fit my arm up in the ceiling which is why I needed the larger box. This box works well but my o...
