From Bitzenburger:
Bitzenburger™ precision die cast clamps are available in three different models:
-
Straight Clamps
For straight fletching -
Right Clamps
For true right helical fletching -
Left Clamps
For true left helical fletching
Our die cast clamps have the following qualities:
Precious Ground
Each clamp is precision ground to assure identical blade matching.
True Helical Fletch
The Right and Left helical clamps are ground with a radius to achieve a true helical fletch.
Hollow Recess
The hollow recess allows for thumb and fingertip control which provides for a tighter grip and more precise finished product.
Graduated Scale
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.
Knife Edge
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!)
Note: The steel plate is cased into the straight clamp, unlike the right and left helical where it is glued on.
