ABSTRACT:
A top insertion, tray stacking wire with coplanar feet extending outwardly in opposite directions at the bottom of the wire with a prong extending laterally outward from the end of each foot at a substantial angle to the plane of the feet. The wire is held in a horizontal disposition for insertion of the feet and attached prongs into a slot aperture in the top edge of a corrugated paperboard tray and the like having a double wall construction. The wire includes a U-shaped body attached to the divergent feet wherein the legs thereof resiliently separate from one another to abut the ends of the slot aperture with the divergent wire feet projecting underneath the ends of the aperture. While the U-shaped body is being pivoted to assume a vertical orientation, the prongs bite into the corrugations of the adjacent wall, simultaneously pressing the pivoting feet into firm engagement against the wall adjacent thereto whereby the stacking wire is maintained in a firm, upright disposition. The prongs bite into the wall corrugations to a sufficient degree to enable one to carry a tray equipped with two such stacking wires, with or without a superimposed second tray when desired.
