Step 3
Cut two pieces of 1 x 2 approximately 4″ longer than the area you previously cut out. Place 1 x 2 on the backside of the wall (or ceiling) and attach with drywall screws as shown.
If the area is less than 3″ in width, you can use just one “backer” 1 x 2 placed in the center. If there is a stud to attach to you may eliminate at least one of the “backers”.
