I have up for bid (24) 11/32". BLACK   Classic Bohning Index Nocks for fletching arrows. With index nocks you can tell were your cock feather is in low light.. (glue on).      These work good on wood shafts "  11/32",  23/64" and on fiberglas, and aluminum arrows. . On the 23/64" shafts they set up on the shoulder.  ALL OF MY NOCKS GO ON A TAPERED  END ON THE SHAFT  (GLUE ON)           Happy bidding
