Sometimes refered to as "coin racks", the 112 and 202 Series Slotted Racks are a great solution for racking thin, round parts. The elongated shape of the slot helps pevent twisting of the parts. They also work well for small panels. If the part is square, turn the part so that the opposing corners fit into the slots. If the part is rectangular use either a 112F or 202F Rack which have a bend in the center of the slot. This bend allows the part to be placed straight side down.
