Product information "Sanlida Crossbow Cocking Aid String Montage"
Replacing your recurve crossbow string is a piece of cake with the help of this Sanlida cocking aid. This tension aid is actually a somewhat longer crossbow string with large rings at the end. You first mount the cocking aid and then cock the bow as you normally would when you want to shoot. Now the bow is under tension and you have enough room to install the original string. You can then relax the bow and remove the cocking aid.
Suitable for almost all recurve crossbows from 120-175 lbs
