3129-80, SLIDABLE TRUCK COVER ASSEMBLY ABSTRACT:, A cover assembly is installable on the open bed of trucks adapted to be mechanically drawn over or withdrawn from the top of the truck bed by means of a pulley operated looped cable attached to a movable tarpaulin. The tarpaulin covers and seals the top portion of the side walls, front and rear walls of the truck when in the drawn position, thereby completely sealing the interior of the truck bed from the outside. The assembly reduces driver fatigue in covering the truck bed as well as reducing the risk of driver injury.
