BPEs Pro-Series Arrow Fletcher lets you fletch your arrows with three or four vanes so that each is consistent with the others. CNC-milled head is accurate to 0.0001 so you can set both the fletching and nock angles with confidence. Indexable shaft support accepts shafts sized from 12/64 to 27/64. Hardened indexing contact points deliver nonwearing accuracy that wont diminish over time. Will allow you to do three-vane fletching at 120 or four-vane fletching at 75 x 150, 60 x 120 and 90 x 90. No ball bearings. Type: Fletching Jigs.
