ABSTRACT:
An industrial sliding door has one or more panel assemblies, each panel assembly having a track panel secured to a header and a swinging panel hinged at the inner edge of the track panel to pivot in either direction about a vertical axis if the swinging panel is impacted by a vehicle such as a fork lift. Both panels can also pivot in at least one direction about a horizontal axis. A rail mounted stationary relative to the doorway at the lower edge of the door holds the lower edge of the door in proximity to the doorway and is disengagable if the door is hit from the opposite side, to permit the door panel assembly to swing about the horizontal axis away from the doorway. The swinging panel is held by a detent in the plane of the track panel in a normal position.
