Review: These are the best for old work. - 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.
Review: Sturdy and Adjustable Two Gang Device Box - I recently used the Southwire Two Gang Device Box for a home wiring project, and it did not disappoint. The adjustable depth feature was incredibly handy, allowing me to fit the box perfectly into the wall without any hassle. The construction is impressively sturdy, which gave me confidence that it would hold up well over time, even with heavy-duty use. It's also very accommodating for different types of wiring, making the installation process much smoother. One thing I particularly liked was how secure the box felt once installed. It didn’t wobble or shift, which is a big plus when you’re dealing with electrical components. The gray color blended nicely with the rest of the installation, maintaining a neat appearance. If I had to point out a small drawback, it would be that the adjustment screws could be a bit more accessible, but this is a minor issue given the overall quality. For anyone tackling a similar project, this device box is a reliable choice.
