Boxes recessed too deep
I've got a bit of a dilemma with walls that are thicker than what the original electrical layout allowed for. All of the boxes (switches, light fixtures, outlets, etc.) are anchored to studs and/or rafters and set at a depth that would be fitting for some thin paneling or drywall. There is now a thick knotty pine tongue and groove planking in place so all of the boxes are now set rather deep, meaning the outlets and switches, etc., will be recessed considerably. When the cover plate is put on it will not draw flush with the outlet or switch. Is there any way to shim the switches, etc., out as opposed to trying to move all of the boxes forward? If not shims do they make/sell switches and outlets for this type of problem? I sure don't want to try and move all of the boxes.
Any help would be appreciated.
