Installation:

Cut Out

NOTE: This is the most important part of the entire installation. If you are not certain whether any obstructions exist behind the desired mounting area, you should start by cutting a small hole in the center of your penciled mounting hole with a drywall saw.

Using the Cut Out dimensions measure and trace a template on the wall in the desired location. Cut along the traced line using a drywall saw or rotary drill. Use a piece of sandpaper to sand down the cut out edge for a smoother contour. (See Diagram 1.)
