    • These are the best for old work.
Size: 2 Gang Style: Original
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. ... show more

    • Fantastic product.
Size: Supports 50 lb - 75 lb Style: Fan & Fixture
I had a ceiling fan box pull out of its place. This product is designed for installing without further damage to your ceiling. It works great! The attachment screws are a little tricky to get at directly. I used a nut driver at first then a screw driver bit to finish and tighten. The metal reinforcement makes it real sturdy. I love that there are bolts with nuts to attach your light fixture. The nuts are nylon locknuts and will never come loose. Installs easily and fast. I highly reccomment this product. ... show more

    • Great product!!!!
Size: Supports 50 lb - 75 lb Style: Fan & Fixture
I was in the skilled trades as an electrician for 40 years I needed to replace an existing ceiling box to hang a ceiling fan. There was no access from above. I cut out the old box and installed this Southwire box. What a great product, someone really put thought into the design. It is very substantial a d easy to use. I highly recommend this product ... show more

    • Great box for old work.
Size: 1 Gang Plus Style: Original
Bought this because I had to add a new outlet and accidentally cut the hole in the drywall too big. Because one side of the hole was against a stud, this worked perfectly to secure in the hole where a standard old work box with flanges that didn't have anything to grab onto. I bought the one that was extra deep, plenty of room for three sets of wires coming in. The box itself is very sturdy too. I did take off one star because the tabs in the back are difficult to remove and they leave behind a triangle that can make it hard to feed the wires past. Just a note, I'm a DIY homeowner and I only had needle nose pliers to get the tabs out. So for more experienced folks with better tools it might be easier. ... show more

    • Great box.
Size: 2 Gang Style: Original
Weird I could not find a box like this at Lowe's or Home Depot. This one was cheap and worked perfect. I installed in a single outlet drywall hole. The old box came out OK (nailed in). I enlarged the drywall hole and the 45 degree screws on this box work well to attach to the stud. Knock-outs pushed out and the Romex came through easy. Both outlets screwed in with good clearance and no edge gaps on the cover plate. ... show more

    • Fantastic option for a post build fix
Size: 1 Gang Style: Original
I had an issue with one of the boxes. Breaking the old box in place and using pliers to pull out the nails then pushing this in and pull the romex through worked fantastic! Very sturdy box, feels a lot more stable than the drywall clamp style or the surface mount style. Definitely would recommend. One thing to note, if you have a double box situation with low voltage on the other side be aware of the depth of the box. It worked for me, but I had to be mindful of the other box. ... show more
