Zenith Bitzenburger Upgrade Kit

The best ad on for a Bitz jig

Allows me better alignment for different arrow diameters. Centers arrow off of pin bushings and shafts. All my Bitz jigs have this upgrade!

Great product!

Upgrade kit was easy to install after watching a short YouTube video, and works exactly as designed. Highly recommend for someone looking to fletch arrows with tight tolerance and consistency.

Great upgrade to an already great product. No problem drilling the Bitz fixture for the included support plate that comes with this kit. It comes with a template that is a sticker, carefully cut out template and stick it on fixture, centerpunched holes and drilled them out with cordless hand drill, no problem. Comes with 2 different inserts for different arrow shaft sizes. You do have to remove your nocks, but the nock receiver is a lot more precise than the original also. Only Cavet I have with this kit is no sleeve included for the x and h nock size arrow shafts.
