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.
A seal member for sealing the gap between first and second surfaces arranged in facing relation to one another, said surfaces being mounted for movement toward and away from one another and being mounted for relative movement in substantially-parallel planes, said seal member comprising:
In a structure having a first member provided with a first surface, and having a second member provided with a second surface, and wherein portions of said first and second surfaces are arranged to face one another, a recess extending into said first member from said first surface, said first and second surfaces being mounted for relative movement substantially-perpendicular and substantially-parallel to at least one of said surfaces, the improvement which comprises:
