This alignment jig helps you install dual gang decora light switches. if you have the switches misaligned you cant get the wall plate cover on. or its tight fitting so the light switches bind. you cant use a wall plate because it covers the install screws for the light switch. this lines them up and leaves screws exposed for securing the switches. just install switches and get them almost tight, toss on the jig and finish tightening the screws. wall plate fits smooth every time. posting link to the levels I ordered from Amazon.
