This is the strongest linear actuator that liftmaster makes. It has a commercial-duty cast-aluminum housing for a rugged yet sleek exterior. A heavy-duty 24VDC continuous-duty motor performs in the most demanding applications. It will operate gates that are up to 18′ long or 1,600LBS. The smooth start/stop operation and mid-travel reversal extend hardware life of the gate and operator. This system has a manual release, battery backup and is solar ready. There is a two-year warranty from Liftmaster as well.
