Model DC-4811 provides an effective and convenient means to secure panel type roll up doors which incorporate a roller track transport mechanism. The inclusion of an adjustable L-bracket allows fitting to roller tracks up to 3in wide. For the highest level of security, mount the switch below any other devices installed on the track while still high enough to keep the cabling off the floor surface.

Mount the magnet on the door so there is a 1/4in to 1/2in spacing between the switch and the magnet when the door is in a closed orientation. Avoid locating the magnet near handle and/or latch to prevent it from being used as a foothold or other type of door closing accessory.
