Add a timer to your door opener for precision timing. Some locations and personal preferences need personal timing. By hooking up this timer to your unit, you can precisely control what time the door opens and closes, or just open at a specific time and let it close automatically at the default setting around 10 pm. Just screw the timer next to the unit and plug in the wires. Long lasting quartz timer is digital and analog for long life and is housed in a protective unbreakable weatherproof box.
Instructions, batteries, screws and wires included.
