Bohning HELIX TOWER Fletching Jig

Unit price  per 

Bohning HELIX TOWER Fletching Jig


Fletch three vanes or feathers at once with Bohning's Tower® Jig! This revolutionary fletching jig provides exceptional adhesion force that is evenly distributed along the base of the vane or feather. You will get consistent angles and perfect 120° spacing. The durable, engineering-grade composite material can be cleaned with acetone to remove adhesive residue. The Tower® Jig is great for single vane repairs too! Available in multiple configurations (see reference chart) for different arrow sizes and fletching angles, from straight fletch up to a 3° right or left helical. All configurations include a base, three sizes of pressure rings to accommodate all arrow diameters, a set of 3 Spacer Plates for an extra .025" (6mm) of space between the nock and vane, and Clamp Release Tape.
