Bitzenburger precision die cast clamps are available in three different models: Straight, Right Helical or Left Helical.
Each clamp is precision ground to assure identical blade matching. The Right and Left helical clamps are ground with a radius to achieve a true helical fletch. The hollow recess allows for thumb and fingertip control which provides for a tighter grip and more precise finished product. The Graduate Scale at the rear of the base of the clamp allows for consistent and accurate spacing of the feathers and vanes from the nock. The knife edge on located on the base of the clamps eliminates build up of surplus glue and provides a clean and professional final product. (No messy arrows!)
