Abstract: A truck bed cover is provided for the covering and protection of loads of varying height. The cover includes a generally rectangular center section of a size adapted to cover the truck bed, surrounded by four outwardly-extending panels or flaps. Each of the flaps is provided with a series of connectors designed to mate with compatible elements located on the truck bed sides. The connectors are arranged on the panels such that the panels may be folded to provide various effective heights for the cover, the folded portions of the panels being maintained in position by complementary fasteners located on the cover. In a preferred embodiment, the connectors are in the form of grommets which mate with studs located on the truck body.
