Abstract: A cargo chock for a cargo bed which has a corrugated liner defining channels and ridges. The chock includes a base having a top with a planar area and a bottom with alternating channels and ridges which mate with the liner of the cargo bed. An upstanding ridge in the form of a cross is arranged on the top. The upstanding ridge includes sides which are normal to the planar area of the top and an upper surface which includes an apex from which the elements of the cross extend downwardly toward the ends thereof. The elements of the cross are aligned parallel to and perpendicular to the channels of the bed, respectively. The element lying parallel to the channels of the cargo bed is displaced laterally to create additional adjustment capability.
