1/2 HP Screw Drive Garage Door Opener


The 3240 1/2 HP Screw Drive Garage Door Opener is smooth-running, even in the most extreme temperatures, and is the perfect choice if you want the latest advancements in smooth-running performance with a completely maintenance-free drive system. Our engineers replaced the two-piece plastic liner and aluminum rail system with a stronger, simpler one-piece galvanized steel rail, resulting in reduced friction and eliminating binding and the need for lubrication. And the 1/2 HP motor is equipped with our patented Motor Vibration Isolation System (MVIS®) to reduce noise and provide smooth operation year after year.

This model has earned the Good Housekeeping seal.
