I recently replaced an electrical receptacle. It was old and the device box was also recessed. So, I added the 1-Gang Outlet Box Spacer Extenders from Home Depot. Now, the receptacle is held tightly in place by the device box rather than against the drywall with a space in between. However, this has revealed that the device box was not mountedparallel with the drywall and the receptacle appears crooked (see photo below). I was thinking of shimming the device box on the side connected to the stud but that would only increase the angle. Does anyone have any suggestions for fixing this angle so that the receptacle and the drywall are parallel?
I find that i can usually manipulate them into alignment.
The tabs on the outlet that the screws go through attaching the outlet to the box are made of somewhat malleable metal.
Turn the breaker off to the circuit so there is not ANY power to the box. You should use a non-contact voltage tester to insure that there is no power in the box to any wires.
Take off the cover plate. I can usually just grab the outlet with my fingers, i reach in as far as i can and try to push the back of the outlet to one side or the other.
In your case you would push the back left side to the right.
Sometimes they are stubborn and do not move easily or i can not get a good finger hold so i carefully use a pair of adjustable pliers or a small pry bar to push the back to the side. ( remember the power should be OFF ) Be careful to not crush/crack the outlet.
It may take little fiddling but you can straighten it out.
At a certain big box home store with blue and white trim, they have a "Silver Steel Wall Plate Spacers" that look like this:
These are purpose made for what you are trying to do. The description reads
