Abstract: A storage rack assembly includes a plurality of vertically disposed corner posts and a plurality of horizontally disposed beams interconnected between the corner posts for defining a box-like structure having a front face and a rear face. A plurality of elongate partition members are interconnected in spaced parallel relationship between a beam forming part of the front face and a beam forming part of the rear face, each partition member comprising a longitudinal base portion, a longitudinal leg portion extending upwardly from the center of the base portion and a pair of longitudinal shoulders extending upwardly from each edge of the base portion. Each partition member further includes longitudinal mating means depending from the center of the base portion for mating with suitable slots formed in the beams of the front and rear faces of the assembly.
