Abstract
A system for selectively locating a door within a frame may include a frame, a door selectively located within the frame and a hinge. The hinge has a frame attachment portion and a door attachment portion. The portions are pivotally connected to one another via a pin. The frame attachment portion and door attachment portion cooperate to cause an outside surface of the door to be flush with an outside surface of the frame when the door is substantially within the frame. The frame attachment portion has a roller flange extending substantially transverse to the frame attachment portion that selectively engages with a roller on the door attachment portion.
