ABSTRACT:
A seal member (11) is adapted to seal the gap or space between a door panel (12) and frame (13) of a roll-up door assembly (10). The improved seal member includes a first portion (34) and a second portion (35). The first portion is mounted on the frame, and the second portion is biased to flexibly engage the outer surface of the door panel. The first portion is formed of a relatively-rigid vinyl, while the second portion is formed of a relatively-flexible vinyl, or may be in the form of a brush. The first portion has a raised abutment surface (42) arranged to engage the door panel, should the door panel move toward the frame, to prevent the second portion from becoming crushed between the first portion and the door. Thus, the second portion is protected from damage, and does not substantially impede vertical movement of the door. The first and second portions may be formed integrally or separately, as desired. In one form, the seal member first portion is adapted to be snapped into engagement with the frame.
