ABSTRACT:
A overhead door assembly which includes a device to maintain the door in a raised position in the door opened position. The door is maintained in a position significantly higher than the position the door would normally assume thus providing an enlarged door opening. The door can be maintained in the raised position by either locating the point of attachment between the load balancing operator cable and the door or by blocking the path of the door in the door guide tracks. Various structures for relocating the cable attachment point and blocking the path of the door are contemplated.
