  • Patent number: 7152377
    Abstract: A door construction is illustrated with plural bumpers formed during the door manufacturing process. Respective sets of edges of the door body, such as trailing edges of door panel sections of the door body and top edges of the door panel sections, may be trimmed to establish the width and the height of the desired door. A closure or spacer member may be used to connect the trimmed edges. The door may be supported by a hinge assembly for pivoting about an upright pivot axis. The door body may be a monolithic one-piece construction, apart from any such closure members, and optional any window and window support. The door body may be formed by rotational molding.
