The Bitzenburger Precision Die Cast Clamp (Left Clamp) is an accessory for the Bitzenburger Fletching Jig designed for archers who apply a left helical or left offset configuration. Constructed from durable, precision die-cast alloy, this secondary or replacement clamp includes a strong permanent magnet that holds the feather or vane securely at the required angle. The contour of the clamp helps impart a leftward spin to the arrow during flight, which enhances stability and improves accuracy, making it ideal for customizing arrows for specific shooting needs.
