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.

Abstract: An anchor member for unitizing a plurality of containers arranged in laterally adjacent and superimposed relationship, the anchor member including a flat body having a single wall portion extending therefrom transversely of one face of the flat body and adapted to be positioned in the space between laterally adjacent containers, and pins or teeth extending from both faces of the body for grippingly engaging the walls of adjacent and superimposed containers.

Abstract: A retaining clip for attachment to a slip sheet used in the stacking and transportation of containers by forklift trucks or the like. A portion of the clip is attached to an edge of the slip sheet tab, and another portion thereof is inserted between, and grippingly engages, adjacent containers on a slip sheet so that the tab of the slip sheet is held up in position to be grasped by the forklift truck.

Abstract: A substantially flat anchor member for positioning at the juncture between a plurality of containers for enabling the same to be moved as a unit. Wall means depending from the anchor member fit between the containers and cleats extending from the body of the anchor member penetrate adjacent containers to secure the same together. Cleats extending from the opposite face of the anchor member body penetrate the bottom of a container or containers placed on top of the anchor member. For open tray type containers used in shipping bottles, cans, etc., complemental retaining wall means extending from the opposite face of the anchor member engage the top of a bottle or can in the tray, thereby holding adjacent trays together.
