Allen 60mm Single Pro-Rachet with Wave Sheave

The Wave Ratchet Sheave has an offset V style grip, made from a hard wearing recycled plastic nylon, which does not have sharp edges that will eat into the rope. Instead, by adjusting the V formation in the sheave to be slightly offset, the ratchet now grips the rope at additional points around the sheave, resulting in 20-40% more grip. However, the new Wave Ratchet not only improves grip but as a result of the design it also allows for less 'jumpy' feel when easing the sheets.
