This has come up before and there is some reason to do it but I never have. I would rather end up a tad in the wall than out of it. When we used to use the mud ring ring for low voltage and nail to the front edge of the stud you were actually out a little farther.Is it good practice to always get mud rings an 1/8th size bigger? For instance, if it's 1/2" drywall, get 5/8" mudrings; if it's 5/8 drywall, get 3/4" mudrings and so on. Couldn't that end up bulging the device out from the wall??
Thanks
Just buy plastic mud rings 1-1/2" deep and use a belt sander on it once the drywall guys are done
A 3/4" ring works perfectly on 5/8" Sheetrock due to the head of the 8/32 screw holding it in place.
