Our Type A ball chain connectors will fit quicklinks up to 3.5 mm in size. #20 Type A connectors are used for both #15 and #20 ball chain (standard industrial use). You will typically need two (2) of these per chain length, and, therefore, four (4) per poi set. Size #13 connectors have a .193 in. hole, which passes a 1/8 in. (3.2 mm) quicklink easily.
