I dont care for those boxes. The clamps are difficult to use, particularly the inset ones and those insets robs you of box volume. The Allied SB-1 slider box is a much better box IMO.Has anyone used the MSB22+ smart boxes? I was thinking about purchasing them, but noticed on the cut sheet that each clamp has either a #14 or #12 label. I'm not sure why they would design them like this. Is it okay to have a 12-2 wire in the #14 clamp?
It already has 22.5 cubic inches which is big for retrofit/old work boxes. that inset makes it easier to get the box into existing finished wall, especially if you have cables entering top and bottom at same time.I dont care for those boxes.

Regarding the specific question, I would say that putting a #12 in the #14 clamp would violate the manufacturers instructions and thus be a 110.3 NEC violation.
I'm gonna say no, and I'm guessing bending radius is why.I'm not sure why they would design them like this. Is it okay to have a 12-2 wire in the #14 clamp?
That looks like a great product. I must admit I have practically zero experience in residential work and have done largely new commercial builds. I know when fishing cables it’s acceptable to have it unsupported, but I’m assuming you still need to have the cable secured to the box. With the allied SB-1 slider box it looks like there are no clamps? With doing “old work” doesn’t it need a clamp?I dont care for those boxes.

Can one clamp support two cables?I use the Arlington version of this box; instead of cable clamps, it has 1/2-3/4 KO’s and comes with a 1/2 NM connector in the box.
They are especially useful when you need to retrofit a larger box in place of an existing box for installation of USB receps or other various smart devices. I’ve used these boxes exclusively in my own house.

Yeah I like those too. The nice thing about the slider box is you can fine tune the depth of the box. With others you have to initially have it stick out a bit because the screws will suck it in as they are tightened. Not a huge deal, just kinda an anal thing if you are a perfectionistI use the Arlington version of this box; instead of cable clamps, it has 1/2-3/4 KO’s and comes with a 1/2 NM connector in the box.

When I do house rewires, I try whenever possible to use the side screw boxes mounted to studs. It takes a bit more time but is a much better job overall than relying on lath or drywall to hold the box. I admit I am quite particular with my old work, I try to do nothing less than the highest quality job.As long as you're against a wood stud or the closed side of a steel stud.
To me, the regular old-work box works just fine anywhere.

MSB22+ smart box
I've used them and like them especially for when the sheetrock or finish carpenter don't know what the final wall treatment is going to be. Easy to get the box back flush after finishing.Has anyone used the MSB22+ smart boxes?
