The Vane Master Pro is designed to fletch all arrow types with minimal adjustment. It will fletch from a 0 to a 5 degree helical both left and right and will fletch all vanes up to 4” in length, as well as, fletching both 3 and 4 fletch arrows. The Vane Master Pro is equipped with vane flat technology. This allows the base of your vane to lay perfectly flat every time using wires with a nonstick coating for clean fletching.
