Abstract
An apparatus for opening and closing an overhead door, having a door assembly for mounting to the overhead door, and an operator for securely engaging the door assembly. The operator has a chassis, and a cable reel rotatably mounted to the chassis and coupled to a main cable. When the main cable is coupled to the door assembly, as the cable reel is rotated in a first direction, the door assembly is drawn towards the operator so as to close the door. The apparatus may include a latch assembly for securing the door assembly to the operator when the door is closed, and a latch release mechanism for selectively disengaging the latch assembly so as to disengage the door assembly from the operator. The overhead door may be biased so that when the latch assembly is disengaged, the overhead door automatically opens.
