Installing new work boxes- distance from stud face


I am installing carlon plastic work boxes for new work. I have been using the nubs on the side of the box so they stick out from the stud but it doesn't look like they stick out more than a 1/4 inch. Sometimes they move more than i wanted them too while nailing them in and also some studs are more round on the edge making this tricky for a noob. I am using 1/2 Sheetrock on the walls and 5/8 on ceiling, how far should the box stick out from the stud? Is it ok if there is a little drywall showing past the box when the face plate goes on? I hope...

Code is a maximum 1/4" setback from non-combustible surface.

A tip some use is to hold a piece of 1/2" plywood to the face of the stud and make the box flush with the plywood. Some even cut an L shaped bracket that will set the box height also.

So if the work box sits inside of the drywall no more than 1/4 that is going to be ok, ideally we want flush.

Man I hate doing things twice, I think the nubs on the box are a complete waste. Who uses 1/4" drywall?!!

Thanks!

It will be OK code-wise, but the device will be spongy when you try to plug in something.

Part of the problem is some 2X4's have rounded corners which will affect the box setback. What would you do if the nubs weren't even there?

Use Slater boxes.

Those nubs are 3/8" -- and as someone else has pointed out, many studs have the corners rounded a bit to minimize the possibility of getting splinters in your hand.

I hold `em from the face of the stud when using standard drywall, and 5/8" when using fire code drywall.

A scrap piece of drywall can help in setting the box depth correctly, OR you can use an adjustable box:

Thanks for the helpful tips everyone. The nubs are 3/8, thanks for pointing that out. If they weren't there i would use one of the helpful tips posted. I am sure they are useful. Like everything it makes sense once you know. I checked my boxes and most are flush with the nub, a few will need redone. The adjustable would have been better for a noob like me, hindsight eh?

I had these problems too. But using a small strip of 1/2 inch plywood or drywall can be pressed on the face of the stud for a better starting point to position the box with.
