perfect for what i needed. the functionality of this design allows you to install the box without cutting a hole in the sheetrock bigger than the box itself. the 45 degree angle mounting screws provided with this are very sharp, and kept the box perfectly in place while mounting it. once mounted, it is strong enough to hang off of it. has several pop open wire entry windows in different locations to customize the installation. nice sturdy box!

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.

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 bought the Smart Box after viewing a demonstration video and I thought to myself, “great! I wouldn’t need to buy (another) hole saw. (I had lost two before ever using them.) The video was helpful. However, it didn’t mention the teeth could actually skip across the wall leaving a clawed arc if you’re not gripping your drill tightly! Tip your drill slightly and hold on tight, then straighten to cut directing into your wall or ceiling. The hole saw will make a perfectly round plug. Don’t take your time cutting your hole as the plastic (or resin) Shark teeth on the hole saw will wear down before you have finished cutting your hole. My Smart Box’s cutting teeth wore down so much it could not cut completely through the drywall’s backing, so make quick work of your hole.I only wished there were instructions on how to easily (or properly) remove the tabs for the wires and install the box. I banged mine up pretty well. The best I can explain is that after removing the cutting bit, bust through one of the tabs along the back or bottom of the box. Bring your wire through the hole box then slide your box into its hole. (It will be a snug fit). A little wiggling and rocking while push will help. Make sure you position the hole you made in the box so that it faces the direction from where your wires come. I used an old work box so it was important to know this before inserting the box as the wires bundled in the wall seemed to dictate how I was going to manage to pull any more wire out after I installed the box.The box has a flange so insert it until the flange is almost against the wall or ceiling and turn the 3 mounting screws until they pull your box completely into its hole, or until the flange is tight against the wall or ceiling. I guess I should mention you should also be mindful of a vapor barrier. I accidentally tore a little hole in ours when I knocked the hole thru the drywall backing when the Shark Tooth hole saw’s teeth wore down.I used the Smart Box to install a wall light in my kids’ bathroom. I had replaced their light when I discovered there was no work box behind it. Just wires capped off and shoved into a jagged hole in the wall. I figured I should bring it up to code and raise the light since it was considerably larger than the original. So large it hung in front of their bathroom mirror. The hole the Smart Box hole saw made left me with a plug that perfectly fit the gaping hole left by the builder. The 3 mounting screws secured the box firmly in place and provided the much needed support for their large wall light. A fire hazard was quickly mitigated!I wanted to use a Smart Box again when I move a light fixture in my kitchen, but wouldn’t you know...one of my hole saws showed up! Lol
