Abstract
Abstract A door holding apparatus holds a door in a preselected position relative to a door support. The apparatus includes a rod which has a first end pivotally connected to the door and a second end for engaging the door or door support. Force exerting apparatus exerts a force against the rod and urges the rod into forcible engagement with the door or door support.
