Lightbulb Floating electrical box

On a project I did a little while ago I was running wires and installing boxes for 120V receptacle and Ethernet (low voltage). One of each box was installed one above the other and do to the difference in width/size of the boxes they didn't line up vertically and looked funny once the wall plates were on. Missed by about 3/4 inch. As the drywall was already on and it was on the right side of a 2X4 just a few inches from a corner (no room to swing a hammer or get a screw gun in) and too close to the other box to use an old-construction/repair box (no drywall to fasten to) I needed a way to mount the box floating in space 3/4 inch off the stud and an inch off the drywall behind it.
What I did was use polyurethane foam in a can (spray insulation) to glue it in place. Worked fantastic.

Just thought I'd share in case anyone else someday has a need for such a thing.

thanks. I know hindsight is 20/20, but you could have had a V8. Carlon 2-Gang Dual Electrical Box and Low-Voltage Bracket-SC200DVR at The Home Depot
