Beiter Tri-liner jig
The Beiter Tri-Liner is used to mark the exact position of vanes (like e.g. Spin Wings™, Kurly Vanes™, Rite Flite Vanes™, ...) on arrow shafts up to 7,2mm (9/32") Nock-out-diameter.
With the Beiter Tri-Liner it is easily possible to adjust the position of fletching in relation to the string, as well as the distance to the end of the shaft.
The Tri-Liner ist can be used for different Vane lengths, for Lefthand or Righthand archers, as well as for Recurve or Compound archers.
In fact the positioning ring allows many different adjustements and an exact orientation of nock and fletching.
