Abstract
A door for selectively covering an opening in a wall has at least one primary door panel movable to substantially cover the wall opening. The door panel has a rear surface facing the wall, an opposing front surface and a pass opening to permit passage therethrough. A frame borders the pass opening and includes a lock jamb having an offset door stop and a complimentary hinge jamb. A pass door for substantially covering the pass opening has a rear surface, a front surface, a first side edge and a second side edge. The first side edge of the pass door is hinged to the hinge jamb to permit the pass door to swing between an open position and a closed position against the offset door stop of the lock jamb. A pin for limiting lateral movement of the second side edge of the closed pass door relative to the lock jamb, has a proximal portion fixed to the offset door stop and a distal portion substantially perpendicular to the offset door stop for engaging the pass door when the pass door is in its closed position. The pass door also includes a latch for engaging the lock jamb to retain the pass door in its closed position.
