3575
The 3/4 HP chain drive opener features LiftMaster's largest and most powerful motor - designed specifically for this model. Faster than other openers, the dependable and ultra-heavy-duty system provides steady performance and lifting power to quickly and safely open even the heaviest garage door. Ultra-quiet, it also features LiftMaster's patented Motor Vibration Isolation System (MVIS).
The model 3575 is loaded with exceptional features. Two 100 watt light bulbs and a delay setting control of 1 1/2 minutes to 4 1/2 minutes allow for 33% more light and better control. Also, advanced electronics now allow you to open and close your garage door from greater distances.
In addition to outstanding features, all LiftMaster operators have numerous safety features to give you peace-of-mind. The Protector System projects an invisible light beam across the inside of the garage door opening by way of two photo eyes at the base of the door. If anything interrupts the beam while the door in going down, the door automatically reverses before making contact. If the beam is obstructed, the door will not close at all. The PosiLock system securely locks your garage door as soon as it goes down. An intruder cannot gain access. Also, a manual release handle releases the door from the operator for manual operation in the case of a power failure.
The 3575 comes with a lifetime motor warranty.
