Abstract
Abstract Adjustable shelving comprising a plurality of posts for supporting shelves in adjustable relation. Each of the shelves includes sleeves at the corners thereof respectively, the sleeves being generally frusto-conical and provided with a split wall so as to permit partial elastic lateral expansion thereof such that each of the sleeves are accurately positionable opposite one another at a common elevation, in surrounding relation, along the respective posts. The split wall elastically accounts for tolerance differences in the configuration of each of the frustoconical sleeves and a frusto-conical support arrangement interpositionable between the sleeves and associated posts.
