ABSTRACT:
An improved joint construction (10) for a roll-up door includes specially-configured upper and lower panel sections (12, 11), a specially-configured hinge member (13) adapted to be longitudinally inserted into operative engagement wiht lower panel section, and a seal member (14) protectively concealed within a recess (73) in the upper panel section. The hinge member is coated with a low friction material to facilitate its longitudinal insertion into operative engagement with the lower panel section, and to facilitate relative movement of the adjacent panel sections. The lower panel section has an upwardly-extending lug (42) which is arranged to enter the recess in the upper panel section and compress the seal member when the adjacent panels are in vertically-aligned relation to one another.
