ABSTRACT:
A box car door seal particularly suited for use on new or reconditioned plug style box car doors having outturned flanges on their outer edges positions an improved elongated flexible resilient gasket for engagement with a sealing surface of a door frame. The elongated flexible gasket takes the form of an elongated flange with a wide base, the flange extending outwardly from the abase in a tapered configuration of a length at least two times the width of the base so as to be able to sealingly engage the sealing surface of the door frame when the box car door is in closed relation thereto and whether or not the box car door is in its normal shape and spaced relation to the door frame or sprung and spaced irregularly with respect to the door frame and particularly outwardly therefrom.
