Liftmaster Screw Drive Openers

Ideal for locations with extreme climates, LiftMaster® screw drive garage door openers are specially engineered to run smoothly and quietly in the coldest and hottest temperatures. Our core innovation? A strong one-piece steel rail that reduces friction and eliminates binding. Each model is also equipped with an electric thermistor that automatically adjusts and increases force as it gets colder, ensuring optimal performance. And the new unenclosed, no-lube drive system means less trapped dirt and debris to cause binding when it’s warmer. It all adds up to superior performance, whatever the temperature.
