Spaced apart annular recesses or ribs are provided on the posts for positive engagement with corresponding ribs or recesses respectively formed on the insides of multi-piece collars which are placed in posi- tion about the posts. A fastening ring either slips over the collar or is screwed upwardly onto the collar to lock it into position and to provide an upwardly facing shelf-supporting surface. Shelf-clamping rings are then screwed downwardly on the collars to abut the top surfaces of the shelves.
