Abstract: An assembly for the production of covers, or toppers, for the truck beds of various sizes and makes of pick-up trucks comprising a preformed shell which serves as a base or body portion for the finished cover, and a support member for the preformed shell which provides means for trimming the shell to a predetermined length and enables the shell to be maintained in a fixed position during fabrication of the completed cover. The preformed shell has an initial length greater than that of the finished cover, and, together with the support member, provides a simple, effective and efficient means for making covers for at least eleven different models and makes of pick-up trucks.

Abstract: A knockdown bed liner assembly for pickup-type trucks comprising interconnectable floor, side and front panels, and a separate tailgate panel. The floor and side panels are shaped to accommodate the wheel wells of a truck, and the floor panel is provided with a unique rib construction to facilitate movement of cargo on the panel and to permit air circulation between the floor panel and the truck bed floor to protect against condensation and rust. The panels are packaged and shipped in knockdown form in a relatively compact easy-to-handle container ready for assembly at the point of use.
