How often does this happen to you: You’re lying in bed and the wife asks, “Honey, did you close the garage door when you came in?” You can’t remember, so you get out of bed to check. You can avoid this whole scenario if you install Xceltronix’s Autocloser.
You need an extra outlet close to your garage door opener, since the Autocloser runs from 110V power. Installation seems simple enough — basically, you mount it to your garage door opener, connect it to the wall button terminals of your garage door opener, and mount a reflector to the J-brace. It monitors the door position by bouncing an infrared signal off the reflector, so you need to do a little adjusting to make sure it knows where the garage door is.
When the door opens the Autocloser starts its timer. When the timer finishes, the Autocloser emits both visible and audible closing alerts and then closes the door by closing the wall button contacts. The timer can be set to close the door after 2, 5, 10, 15, or 20 minutes, and you can override it with a disable button if you want the door to stay open.
The Autocloser retails on its own site for $50, but be careful — some retailers choose to charge more.
