"spreader bars"ultramegabob said:I use a bracket to span steel studs and mount my 4" boxes with mudrings on, I think they are made by caddy or b-line, it makes the box really firm for when a cord is pushed into the device.

LarryFine said:One quick side note: I've always found that a mudring 1/8" deeper than the nominal wall thickness fits perfectly. In other words, a 5/8" ring for 1/2" drywall. That allows for the box's 8-32 screw heads and such.
What!! They can't even cut out around the boxes right. What makes you think they'll be able to make two divots? Seriously, that's a pipe dream?peter said:I basically agree with Mr. Fine's idea of using 5/8" "mudrings" for 1/2" drywall. But the problem there is that the sheetrockers could easily take the time to create a little divot on the back of the gypsum board where the 8-32 screws go.
Uh... cost. The one's you propose are about triple the cost. Millions and millions of boxes have been installed with ordinary stamped mud rings with success, so there's no reason to use a more expensive part to save another trade effort or labor.peter said:And why use "mudrings"? These are designed for plaster applications. Masonary rings have straight edges or sharp 90? angles so there is no unnecessary gap between the metal and the gypsum.
