1/2 HP Screw Drive Garage Door Opener
Get optimal performance no matter what climate you live in. Our 3240 1/2 HP screw drive opener is specially engineered to run smoothly and quietly in even the coldest and hottest temperatures
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.
Our newest opener – the LiftMaster Elite Series™ 3840 – is the only screw drive opener on the market with fully integrated battery backup technology. The EverCharge® Standby Power System will continue to operate even when the power is out, ensuring you always have access to your garage and home. It also comes with our premier line of accessories for the ultimate in garage access.
