Not one stuck proud of the wall, and nearly all were a perfect fit.
Garvin plaster rings plus#
You lose 1/8" from the screws plus another 1/16" for the sheet metal thickness.

They all ended up 3/16" to 1/4" recessed even with the boxes mounted properly-code-legal but just barely. Then, to be safe, I picked mud rings the same nominal size as the drywall. Of course, adjustable rings would be great, but nowhere local carries them unfortunately.Ĭlick to expand.I rewired most of my house with square boxes and mud rings and spent way too much time researching this same question. So seems less precise, but more easily fixable if using the same size. If the ring is sized to the drywall size and is recessed a bit it is easier to put a few of the shims in when installing the switches and outlets. On the other hand, if for some reason I get everything flush when installing, I could have a mudring that sticks out past the drywall slightly which can't be fixed. On one hand, I would love for it to be flush out of the gate, which is why people upsize. Meaning, for 1/2" drywall, using 5/8" vs. I have read that there is a very testy debate going on for years about sizing up vs. Old work plastic is actually fine with me, but for new work, metal is where I will be at. I swore off plastic after years of being frustrated at the terrible declining quality of them as years go by. I am going to be using mud rings in metal boxes for the first time as I am remodeling.
