Step 4
The CAS mounting frame has a series of spring-loaded clamps around its perimeter. These are designed to fold shut as you push the mounting frame into the hole and spring open once inside, thus holding the mounting frame in the wall. Insert the mounting frame into the cutout, making sure that you run the speaker wire in through the rear opening. Starting from the lower right-hand corner and working in a counterclockwise fashion, hand-tighten each of the 12 clamp screws (ONLY until almost snug). If needed, adjust the mounting frame so it is level and centered in the cutout. Go around once more and hand-tighten each screw as needed. Before proceeding to Step 5, verify that each of the clamp screws is tight.
