Excalibur's C2 crank is the perfect solution for hunters who have difficulty drawing high poundage crossbows. The C2 crank dramatically reduces the effort required to draw any current Excalibur crossbow model, as well as guaranteeing consistent string alignment. Unlike cumbersome permanently mounted cranks, it detaches in seconds when the bow is cocked, and is carried separately in a pack or pocket. Constructed of high strength aluminum alloys and machined to tightest tolerances, it will provide years of trouble free service. Please note that this Cranking aid is for use with Excalibur's thumbhole or 2008 and newer traditional stocks identified by five diagonal slash marks located on the forend on either side of the trigger. This will not fit Relayer Y25.
