ABSTRACT:
A door holdback device holds a door or panel in open position. It may be mounted upon the wall of a conventional boxlike highway trailer and is automatically retractable to an inoperative position. The holdback device has a primary wire loop extending from the wall, said primary loop being integrally attached to two secondary wire loops, which are then secured to the interior of the wall. The secondary wire loops are internally stressed to retract the primary loop when not in use. A second embodiment employs an internally stressed primary loop which moves about its supporting mount to assume an operative position.
