These nocks are tapered on the inside and are often used with our NNI aluminum nock adaptors. Some builders also use these with wood dowels. TIP: put the dowel in a pencil sharpener to make a point.

Largest inside diameter = .265" (tapered to a point)
NOK30 will fit over: NNI20, NNI30, NNI40

We are gradually eliminating this fitting as the machined spar nocks and end caps are becoming more popular. Supply is limited.
