Abstract: An apparatus for protecting the upper portions of the side walls of a vehicle cargo bed is disclosed. The apparatus includes an elongate body having a medial section, a first end, and a second end, both ends extending downwardly from the medial section. The first end includes a magnet system which enables its attachment to a vehicle bed wall without mechanical fasteners. The second end includes a hook member adapted to engage the ledge portion normally found in most vehicle cargo beds. The entire apparatus is preferably of one-piece construction, and manufactured of rubber. It also includes a flexible joint between the first end and medial section to facilitate use of the apparatus with walls of different thickness. Finally, the top of the medial section includes a plurality of longitudinally extending ribs designed as shock absorbers for any cargo or objects positioned thereon.
