These finger-like dividers have the same cross-sectional spec as flat crossbar and 1″ Grid. So Crossbar / Grid hooks mount directly. The divider “fingers” can separate oversize related items, or as in this case, allow hanging of a family of items in different colors. Dividers can be inserted in the backrail at any slot location for tight or loose spacing. CLICK the thumbnail for a better look at the Crossbar / Grid Hook with Metal Plate Label Holder.
