Excalibur's C2 Crank is the perfect solution for hunters who have difficulty drawing high poundage crossbows. Features: - Guarantees consistent string alignment for best accuracy - Minimal effort required to cock any current model crossbow (These are the 2008 and newer stocks, either with the thumbhole, or 5 diagonal slash marks located on either side of the trigger, also fits the Vixen II) - Detaches in seconds, removing unnecessary weight from the crossbow unlike permanently mounted cranks - Constructed of high-strength light-weight aluminum alloys to reduce weight - Machined to the tightest tolerances to provide years of trouble-free service
