LiftMaster's solid-steel drive screw is maintenance-free. Encased in a wear-resistant channel that eliminates metal-to-metal contact for longer drive mechanism life and quiet operation, it never needs lubrication - ever! This garage door opener is also equipped with a Motor Vibration Isolation System (MVIS)...a revolutionary "floating motor" design that eliminates powerhead vibration, resulting in smooth, quiet performance.
This model comes with a lifetime warranty on the motor. Also comes with standard three button transmitter. |
