LiftMaster Premium 8355

Quiet, Smooth, and Internet-Capable

Quiet and smooth, yet as tough as a steel-belted tire, the 8355 1/2 HP Belt Drive Garage Door Opener is the perfect choice if you want both quiet and smooth-running reliability, or simply have rooms positioned above your garage. The 1/2 HP heavy-duty motor is equipped with our patented Motor Vibration Isolation System (MVIS) that eliminates powerhead vibration for reduced noise. It also features a solid-steel T-rail with automatic belt tensioner on the trolley, and an enhanced belt drive system for a more secure belt grip.
