Abstract: A door support for holding open a door equipped with a hydraulic-type closure having a pair of closure arms and a hydraulic element comprises first and second channel members, each having a top side, a hinged wall and latching wall, with both walls spaced apart and extending perpendicular from the top side, forming a generally rectangular configuration. A hinge, which is fixedly attached to the hinged walls of the first and second channel members, permits rotation of the channel members about the longitudinal axis thereof for alignment of the channel members with that of the selective positioning of the closure arms. An elongate, flexible band, having a latching end and a secured end, and a bolt or cylindrical, elongate pin positioned through the apertures of the latching end and latching wall of the second channel member secures or locks the channel members in a stationary position to prevent lateral movement of the closure arms.
