Elite CSW 200 UL DM Chamberlain Elite CSW 200 Commercial Swing Gate Operator with two (2) 1/2 hp motors. One motor opens the gate and the other one closes it, unlike any other operator in the world. The Elite CSW-200-UL-DM™ uses a unique, patented, dual motor feature. Because of this feature the gate operator can function in less than ideal conditions, such as desert environments, and not overheat the motors. The Chamberlain Elite CSW-200-UL-DM™ gate operator is specified for use at heavily accessed high traffic areas such as multiple family communities with 250 or more homes in high ambient temperature applications.
