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

I have installed a lot of retro-fit fan boxes in old work, typically the t-brace style. This was my first of this kind. Much easier to install and just as sturdy. I like the fact that I don't have to worry about blindly catching the joists with teeth, or risk putting excess pressure on the ceiling drywall causing nail pops. The box is heavy duty plastic, the three lag screws really bite the joist. I'm quite confident it's not going anywhere.

I bought this in case the standard way of retro-fitting a ceiling mount for a fan would not work. Glad I did - there were technical limitations in my scenario that prevented the retro-fan box brace from fitting in my required location.Luckily enough I had this box on standby and it worked out great. Only a single-sided mounting is needed and once the screws are fully driven in, it's very stable.The only issue I found is that the box tended to want to move as the screws are being driven into the joist. A pilot hole will help here. I also temporarily added some large washers around the larger fan mount screws to prevent the box pulling past the surface of the drywall, which seemed to help.

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.

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.

Began installing a Hunter 42” fan and realized really quickly that the outlet box already installed wasn’t going to cut it. After a couple of other options/tries, I got this one. The angled screws make install a cinch and this baby ain’t moving even a smidge. Rock solid.

Excelente, demasiado grande, acostumbrado a las de México, pero cumple perfectamente

This type of gang box is very easy to use, and easy to install in any home wiring application. It's also competively priced.

I was a little worried by the reviews as this was going to be my very first DiY attempt, and I bought two of these so there was two opportunities for my to mess up! But these were surprisingly easy to use and everything went smoothly with them, I have no idea how some were able to grind the teeth all the way down. Would definitely purchase again and recommend them.

Wish they sold these locally. Bought them in 1-4 gang sizes and have always been a+. They're deeper than the metal boxes so a series of larger smart switches are easier to work with too

Needed this to upgrade a wall outlet to a triple. Very easy to install. Happy with this product.
