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.

Perfectly placed mounting screws. Deep box, plenty of room for everything 4 circuits would need. Correct, industry standard hole sizes for receptacles/switches. Thick material.

I recently purchased a small shop to work on cars in. The shop is about 45 minutes from my house, so I wanted to add in a little apartment in the event I decided to work late. The existing shop had boxes that I have been using inside the living area, but I needed stronger boxes for the shop. That is where these come in. Pros: - Durability: These things are quality boxes. The difference between these and the blue, nail in kind is like night and day. These will hold up very well in a shop environment. - Ease of Use in Tight Spaces: Unlike the nail in type where you need sapce to hammer in the nails, these can fit in existing walls very easily. Just cut the drywall (or whatever material you have for your wall) slightly smaller than the box so it holds it in place, then screw it into the stud. - Marked location for wires: The wire pass throughs are marked for 12 or 14 guage wire, with an offset for each. Not something necessary, but it was a nice touch. Cons: - I found it difficult to get the box to stay in place while I screwed it in. The screws want to pull the box back. When trying to use these on open walls, you'll need to really hold it in place. It would be nice to have a set of teeth on the side against the stud to hold it in place. - Pass-throughs: These are the kind that you can press a wire in and have it lock in place. This is nice to keep it in while you are wiring, but I'm not a fan of these. They are hard to use and even harder to push excess length back in. They were also very hard to snap off if you wanted to remove them - Price: If these are not on sale or marked down, the $9 price is a pricier than going with the hammer on style. I got mine at around$2.50 ea, which was good pricing. This is also true if you are not needing anything too strong. - Useage: These are made for wood studs. If you need something that attaches to other material or do not have access to the stud, these are not for you. For my shop project, these work great! I know these are strong enough to withstand the constant use and potential hits that you find in a shop environment without breaking. I'd probably use these for walls that I'd have to cut sheetrock as well. This is a good buy in my opinion.

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

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.

I have been a commercial electrician for many years doing mostly large commercial jobs (Hotels, Cell store conversions from grocery stores, etc.). I am now an estimator but do a lot of electrical for family, church, and inspect commercial jobs for the construction company that I work for. Southwire was picked up by Lowes several years ago and they had some problems with defective products that were recalled (mostly digital meters/testers). Well Lowes got rid of them and went with Klein and Home Depot greatly reduced their Klein and now have Milwaukee. That being said, you wonder how such a great box came from Southwire! Well, Southwire bought Madision Electrical and now if you look up that 2 gang box under Madison....it looks EXACTLY the same...HMMMMM? This box is about $2 cheaper than the Madison brand. What makes this box so good is: 1) Quality - this is a very sturdy and thick PVC box. 2) Being sturdier, the device 6/32 mounting holes are much more durable (why you should NEVER use a fiberglass box!). 3) The two angled screws are designed to end up a bit recessed so that a short won't make contact with one of those screws. That would be bad as the current would not be going to ground to trip the breaker, but through a screw which turns into a cal rod inside your stud - yes, that would be VERY bad! 4) Those screws hold that box very tightly against the stud and thereby makes the box stable when plugging or unplugging a plug from the outlets. My daughter's house needed some upgrades and these boxes make the job easy. Easy to take a 1 gang box and replace it with a 2 gang box like this without having to cut the walls open other and enlarging for the box size. The NM clamps will need to be pre-opened with a fairly large flat-blade screwdriver - What you had on the other side! Don't pay any attention to the 10, 12 and 14 embossing on the back...each one of those openings/clamps are the exact same size! Not sure what they were thinking there. Update: I find that before installing, grab the box carefully without your hand being near the soon to be protruding screws and use a drill driver to spin the screws in reverse while pushing will pilot the holes and when you actually go to screw it in it will not want to wander further into the wall since you will have virtually no resistance before the screws tips bite into the wall stud.

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.
