ABSTRACT:
A loading dock door seal structure wherein compressible members or pads are located adjacent the top and sides of the door to engage the rear end of a truck cargo body that is backed into loading and unloading position. The pads serve to provide a seal, however, they are spaced outwardly away from the wall of the building adjacent the door frame to leave gaps. Brackets are provided at the top and sides of the door frame and secured thereto, but extend outward and have lateral legs parallel to the building wall that serve as a mount for the seal pads. The brackets also have longitudinal legs extending perpendicular to the doorframe and outwardly therefrom in the gap between the pads and the doorframe. Flexible fabric seal strips are secured to the longitudinal legs of the bracket to close the gaps between the pads and the wall building.
