This mechanical device is designed primarily to assist the bow technician to change the string and cables on the Excalibur crossbow. It is capable of handling any of their models, including the TwinStrike. It can also be used for the same purpose on vertical youth bows. Another purpose for this mechanical device is to check timing and poundage on various crossbows.
It is made of steel tubing, powder-coated, and we use an acme thread screw with an 8” aluminum hand wheel to aide with the high poundage of crossbows.
