Tower® Jigs

Write a Review

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.

    Crossbow Bolt Fletching

    The Bohning Tower Jig for crossbows was easy to set up and easy to use. It was made easy the help of videos that Bohning makes available to Customers. Just cleaned and refletched 10 TenPoint bolts/arrows with ease. Thankyou!
