Motor housing for a garage door operator

An improved garage door opener which has an all plastic outer case in which is mounted a metal motor supporting bracket so as to add strength and rigidity. The unit utilizes a cable drive system which moves in a vertical loop which eliminates side to side racking of the rail and which allows a less expensive rail such as a tube to be used. The all plastic housing is designed so that when the cover is removed all components are accessible and the entire operator is easily serviced, the components fit into nested areas that are molded into the plastic housing. The limit and force adjustments are conveniently located and identified on the outside of the housing. A simplified improved hanging bracket is provided wherein the hanging bracket is attached to the metal motor supporting bracket which supports the motor and the gear housing on opposite sides thereof.
