Just what the doctor ordered
These were just what the doctor ordered for my garage. I padded out the wall with firring strips and put up pegboard. I had a 4 gang, a 2 gang and two single boxes that needed brought out. These worked perfectly and the way they lock together in ganged boxes is brilliant. I would definitely recommend these to everyone.

These were exactly what I needed to bring the outlet flush with the new shiplap wall! Would have looked so awful if i hadn't used these! Easy to self install, only took a few minutes!

    Fit great and did what is supposed to do. I have never been disappointed with Carlon products...but buy longer screws.
    I am glad these were in stock as I wanted to finish this project. I added three sets of these to three double gang receptacle boxes after a remodel. I had added some 1/2 thick wood over existing drywall. These boxes assembled as instructed and fit perfectly. After reading a previous reviewers complaint of screws being too short, I did buy, at Home Depot, a $10 assortment box of various length screws made for electrical boxes. I needed longer screws than what was included. The included screws may be fine for thinner material. So it cost another $10 but I have extra screws I'll use in the future for other electrical projects.

      The customary gang box extenion rings were an affordable, elegant solution that electricians used for years. This ridiculous replacement must have been the brainchild of a junior designer and junior product manager. It is a blatant effort to make $3 instead of $1 from naive DIYers. Home Depot is an accomplice as they no longer stock the former in stores. The product is fundamentally flawed. When halved for a single receptacle gang box the extender can't be centered because of its tabs. More importantly, the extender won't accommodate a bulky GFCI-sized receptacle without rubbing the wire contacts! See photo.

        Product was easy to install. Supplied screws were too short for the shiplap I installed, only 1 3/8" long, I bought 2" screws and they did the job.
