Introducing our innovative EverChargeTM  Battery Backup System

  • Safety and security features will continue to operate, ensuring your family is still protected in a power failure
  • Always charged and ready - no additional outlets are needed

Key Benefits

  • Powerful DC motor. (quietest on the market)
  • Only built-in battery back-up system on the market
  • Smart Control PanelTM - displays time, temperature and important system status messages, making it easier to maintain your system. Also turns on garage door opener lights automatically when you enter a dark garage - hands free
  • Premium Remote Control - the only remote control that automatically lights up as you bring your hand nearby, so you'll always know which button to press, even in the dark
  • Security+ features.
  • Solid steel one piece T-rail runs from motor to door. This design is much more durable and more trouble-free than systems that come in short pieces and have to be assembled.
  • Automatic light delay. Two lights turn on when door is opened or closed and turn off after 4-1/2 minutes.
  • Safe! With the protector system projecting an infra-red beam across the inside of the door opening, if anything interrupts the beam while the door is going down the door automatically reverses before making contact. As a secondary measure the opener also has adjustable force settings which cause the door to reverse if it senses resistance due to coming into contact with something or someone.
  • Home-link compatible
  • A full range of accessories is available.
  • Lifetime warranty on motor and belt.  5 years on all other components.   1 year on battery backup.
