Installation
Install the door control within sight of the door at a minimum height of 5 feet (1.5 m) where small
children cannot reach, and away from the moving parts of the door. For gang box installations it is not
necessary to drill holes or install the drywall anchors. Use the existing holes in the gang box.
NOTE: Pre-wiring means that your garage already has wires installed for the door control.
