IDEAL Industries 172451L Spacer Shim 25/Pack

These things are lifesavers but they're expensive. If you're looking at these, you know what they do. They make properly installing/leveling switches a breeze under less than optimal drywall mudding jobs. All I can say is I installed these in 4 light switches and they work perfectly. One pack should be a lifetime supply lol.

These are absolutely amazing! Took care of some outlets on a wall covered in tongue and groove wood. Would never have got them put on without these since the wall was not uniform.

These work great
