ABSTRACT:
A sectional door such as a garage door of the type having a plurality of hingedly connected panels adapted to be pivoted relative to one another generally about interior edges of facing lateral ends during opening and closure of the door. One of each pair of facing ends of the panels is equipped with a first rail having a front wall and defining an interior pocket. The facing end of the adjacent panel is equipped with a second rail having an arcuate segment extending into the pocket of the first rail in overlapping relationship to the front wall thereof when the adjacent panels are in aligned orientation. When the adjacent panels are pivoted relative to one another generally about their interior edges, the arcuate segment of the second rail moves outward of the pocket of the first rail to span the angular gap formed between the facing ends of the adjacent panels.
