Standard Features:

  • LiftMaster® 1/2 HP AC motor belt drive system delivers smooth-running power and reliable performance year after year
  • MyQ® technology lets your customers monitor and control their garage door and house lights remotely by using a smartphone, tablet or computer (LiftMaster® Internet Gateway accessory required). The LiftMaster® Internet Gateway is only compatible with LiftMaster® garage door opener models 8355, 8360, 8550 and 8500
  • Security+ 2.0™ technology changes to a new code with every click, transmitting multiple frequencies and ensures operating consistency and extended range even in the toughest interference areas
  • Motor Vibration Isolation System (MVIS®) delivers smooth, quiet performance. A perfect choice for homes with a living space above or next to the garage

  • Auto-force allows the garage door opener to adapt to weather and changing environmental conditions, ensuring optimal performance and eliminating the need for manual adjustments
  • Energy efficient operation consumes up to 75% less power in standby mode


Safety Features:

  • The Protector System® safety sensors project an invisible light beam across the garage door opening and automatically reverses the door if anything interrupts the beam while door is going down. Opener lights turn on automatically when The Protector System’s infrared beam is broken
  • PosiLock® system electronically secures a closed door and monitors against a forced opening. When the door is down, it is securely locked. If a forced opening is detected, it automatically reactivates the opener to the closed position
  • Alert-2-Close warning system provides UL325-compliant audible and visual warnings that the garage door is about to close when using MyQ® technology or a Timer-to-Close-enabled control panel (sold separately) (Alert-2-Close applications are for sectional doors only, not one-piece doors)
