How many times have you been gripped with the sudden realization that you may have forgotten to close your garage door? It's a pretty common mistake, but it can be a costly one, since that open expanse can be an enticing lure to thieves. Make sure the largest door to your home is closed securely with the automatic Garage Door Closer, which triggers your garage door opener automatically after a user-specified amount of time if left open. What's Included # Wall console # Garage sensor # Mounting tape # Instructions # Mounting screws # Connecting wire # 3-volt lithium battery Mount the sensor on your garage door using the included mounting tape or screws. When the door is closed, the detection rod is retracted; when the door is open, the detection rod is extended and sends a wireless signal to the wall console, which in turn triggers your garage door opener to shut the door. Planning to work in the garage for a while? A single button press locks the receiver so it won't close when you don't want it to. Since it has a built-in antenna, the included wall console can accept commands sent by a keychain remote, sold separately. The wall console's learning function makes connection easy.
