ABSTRACT:
Injection molded plastic doors having only one face of the door exposed to view in an intended installation are prepared by injection molding a foam plastic door and providing a box beam generally centrally disposed within the door on the usually nonvisible face. Lightweight and high strength are obtained. Such doors are very satisfactory for folding closet door applications.
