Safety and Security

  • Safeguard your household with Security+ 2.0®—with every click, a new code is sent to the Garage Door Opener, so the door opens only for you.
  • Lock down your garage door and electronically monitor against a forced opening with PosiLock®.
  • Stay out of harms way with audio and visual warnings when the garage door is about to close.
  • Remain safe with the Protector System. It projects a light beam across the garage door opening, preventing it from closing if anything interrupts it.
