Beltdrive motors have the quietest operation of any garage door opener. This makes it an ideal motor choice if your garage is located next to an office or bedroom.
Security+ 2.0® safeguards your household – with every click of the remote control, a brand new security code is sent to the garage door opener so that the door opens only for you. This technology makes it impossible for burglars to break into your home with stolen codes.
PosiLock® electronically locks down your closed door against forced entry.
Timer-to-Close remembers to close your garage door when you forget. Activate this system and automatically close your door after a pre-programmed number of minutes. (Models 8550 & 8557 only)
Alert-2-Close warning system provides audible and visual warnings when the garage door is about to close when using MyQ Technology or Timer-to-Close.
Motion detector system activates the garage door opener lights as soon as you walk in so you’ll never need to fumble in the dark again.
The Protector System® protects pets, children, and vehicles from the closing door with safety sensors that project an infrared light beam across the garage door to automatically reverse the door if anything interrupts the beam.
