Southwire Electrical Box for Ceiling Fan, Light Fixture, 50lb Ceiling Fan and 75lb Light Fixture Support, Depth Adjustable, Gray, MSBFAN

Absolutely love these. Easy to install and extremely sturdy. Can’t find anything close to this in stores.

This is a must-have tool. Very clever and well-thought-out design. It worked perfectly for cutting the opening for a light fixture and made the job quick and clean. The plastic guide pieces are especially smart—I only wish it were possible to order those separately and reuse the saw, because that would make this even better. Overall, this is a great product and absolutely worth it. Highly recommend.

These are amazing for knpcking out old bakelite round boxes and replacing them with something beefier. Much beefier. Super easy to install with impact. Everythings gotta be fan rated these days

Was a bit hard to install because the screws have a hard time going into the stud and the angle is quite difficult. The screws and bolts are made of very hard metal that is resistant to stripping. I ended up using a 8mm hex socket to try and tighten the screws and it ruined my hex socket. Had to borrow a friend's 8mm and it started stripping that socket too!! Not happy about that, but overall it works well, very sturdy plastic that is holding up my ceiling fan.

I had an existing old plastic box shatter and needed a replacement that could fit within the existing hole in the ceiling. This box was excellent quality, the screws were a little difficult to drill into the joist but the end result was excellent. No trimming of the existing hole was necessary.

Sturdier mount than other surface mount boxes I have used -- just need to be next to a stud -- much much better for outlets. Some internal space given up for the mounting, but I will definitely use these again for existing work additions.

Fould the product work as it was intended for. Very strong plastic with metal reinforcement. Had no problem holding a 52" ceiling fan.

Great product, makes changing from 1 gang to 2 gang so simple.

These worked exactly as advertised. I had great success going through 1/2 drywall. The cutters do wear as they cut but as long as you go slow with proper pressure it’s works perfectly. Will buy this style anytime I need

Functionality, value for money. Perfect size for what I needed

what adjustment, over priced only adjusts if I want to modify it

This box is perfect for replacing a single gang box with a double

I was ready to give this a great review as installing the box into the wall was easy and there is tons of room in the box. The problems for me started when I started to install switches and an outlet. The outlet is old but the switches were new. When installing the outlet into the box a screw head snapped off. Initially I thought it was just an old screw but then one of the new screws also snapped. I realized that the holes were not drilled deep enough so the screws bottomed out. I was able to get one out but the other was too deep inside the hole. I managed to drill out and use a larger screw temporarily but now I need to rip everything apart and start again. If you get this test the holes before installing and drill out if needed. Update: Ended up ordering another one as I can't find anything similar. Tested all the holes and they were all fine so guess I just had a bad one the first time round.
