ABSTRACT:
A bumper seal to be disposed on the exterior of a building at the lower edge of a doorway and against which a truck or trailer can back to seal its deck edge against the building. It comprises a resiliently yieldable and compressible sealing body member extending transversely below the opening between two bumper blocks disposed at opposite sides of the opening. The seal is removably mounted so it can be replaced when worn. In addition, it is so mounted that a dock plate can be positioned thereover and will interfit with its mounting means to prevent displacement of the plate. Also, the sealing body is ventilated to facilitate compression and expansion.
