Screw-Lock 5 mm Shelf Support Pin Set
A snap-off sprue of four gusseted L-bracket shelf supports for kitchen cabinets with standard 5 mm shelf-pin holes. Each one has a 9 mm octagonal pin measuring 4.6 mm across the flats and 5 mm across the corners, plus an 18 x 10 mm shelf seat with a 4 mm through-hole: drive a #6 (3.5 mm) screw up into the shelf so it can't tip or slide off. The pieces print flat, so shelf load goes along the layers, not across them.
