Abstract
Abstract Resin impregnated wood fibrous material is molded to form a rectangular deck member and a set of separate elongated hollow leg members. The deck member has a generally uniform wall thickness and defines parallel spaced downwardly projecting reinforcing ribs, and the side walls of each of the leg members have teeth-like projections which extend upwardly between the ribs. The leg members are spaced laterally across the deck member and are secured to the underneath surface of the deck member by a waterproof adhesive. The leg members have outer surfaces perpendicular to the deck member to provide for storing loaded pallets within a rack, and define longitudinally spaced recesses to provide for four-way entry by a fork lift truck. The bottom wall portion forming each recess is spaced from the underneath surface of the deck member to define a longitudinally extending chamber within each leg member for receiving an optional rigid longitudinally extending reinforcing member.
