ABSTRACT:
A barn door includes vertical members at its ends and lateral members extended between the vertical members which the vertical and lateral members being interlocked where they meet. To this end, the vertical members are channel-shaped, each having a front and a rear wall along with a end wall that connects the front and rear walls, it being formed integral with both. Each vertical member has vertical ribs which project toward each other from its front and rear walls. The lateral members, on the other hand, have vertical slots in their side walls. The ribs of the vertical members snap into the slots of the lateral members and this interlocks the vertical and lateral members. The joints so formed are rendered more secure with screws which pass through the front and end walls of the vertical members and into the side walls of the lateral members. A siding material is attached to the lateral members and at its ends projects under a lip on the front walls of the vertical members. The door so formed is hung from trolleys which roll in a track.
