ABSTRACT:
In a shelving system having both vertical and oblique supports for removable shelves, identical shelves are interchangeably usable on either support by reason of the fact that mounting slots on the oblique support are farther apart than the mounting slots on the vertical support. The tabs on the shelves cooperate with these slots in two different ways, depending on the slot spacing, thereby automatically insuring the proper shelf orientation, irrespective of the support.
