Abstract: A truck bed liner including an integrally formed bottom wall, front wall and opposed side walls, in which each of the opposed side walls, and preferably the front wall, terminate in top edge portions forming outwardly projecting hook-shaped flanges adapted to snap-fasten over the corresponding top ledges and free rims of the corresponding side walls and front wall of a truck bed within which the liner fits.

Abstract: A truck bed liner comprising a tailgate liner having top and bottom hook-shaped flanges adapted to conform to and receive the top and bottom edge surfaces of the tailgate of a truck bed so that the tailgate liner may be snap-fastened to cover the interior surface of the tailgate, without any separate or independent fastener members.The truck bed liner also includes transversely spaced longitudinal rib members having widthwise dimensions greater than the width of any longitudinal rib members on the bottom wall of a truck bed, to provide longitudinal ventilation spaces between the bottom wall of the truck bed liner and the bottom wall of the truck bed.
