ABSTRACT An improved closure operator as for example for a garage door opener wherein a motor is coupled to the drive shaft of the door at one end thereof to drive pull-up and pull-down pulleys and a clutch mechanism is provided between the drive motor and the drive shaft which can be decoupled by moving a lever arm so as to disconnect the motor from the drive shaft to allow the door to be manually opened or closed as, for example, in the event of power failure. The unit results in a substantial simplification over prior art garage door operators which require a rail and trolley mechanism for opening and closing the door.
