Step 1: Cut out the opening

cut out hole «»
Locate the wall studs with a stud sensor or hammer and nail. Then, use a level to draw a 14¼-inch square onto the wall between the two studs. Cut out the opening with a drywall saw; work carefully to make sure you don't cut into electrical wiring. (If you find some, you'll have to push it aside or reroute it.)
