Abstract
A fire lintel for a freight elevator pass door that provides a fire stop in the gap between the door opening header and the upper panel of the pass door and that is displaceable for passage of the door above into the gap when the door above opens. Two embodiments of the fire lintel are characterized by overlapping baffle-like elements that afford a high resistance to the passage of gases into the hoistway in the event of a fire.
