A half-shell with a divider forms the basic open bench rack. A second shell can become a cover, changing the assembled unit into an enclosed, stackable format. The manufacturer brochure explicitly describes ten basic open racks or five covered racks from a carton.

Dividers are labeled and writable, and the perforated upper divider can be converted for lower support when the configuration calls for it. The covered arrangement encloses the tubes and supports stacking for storage.
