The CROSSBOW BITZ KNOB is designed as a direct replacement for the original OEM knob. The knob boasts two vane spacing options, facilitating consistent setups for 3-vane (120-degree) and 4-vane (90-degree) configurations. It's engineered to align and retain most crossbow bolt/arrow moon drivers and nocks, ensuring the most consistent and repeatable fletching. Additionally, the knob includes a set screw for single vane repair alignment, allowing for adjustments without the need to rotate the nock.
