YOUR SECURITY, OUR PRIORITY!

The Protector System®

Projects an invisible light beam across the garage door opening and automatically reverse the door if anything interrupts the beam while the door is going down. Sensing technology will stop the door from closing if contact is made with a person or object. If the beam is obstructed, the door will not close.
