Designed for mainsheet and spinnaker applications the Pro-Ratchet is the lightest in its class. The fully composite sheave offers strength and durability without compromise of weight. Not limited by conventional machining angles the sheave is engineered to maximise grip when the ratchet is on, yet allow less grip when the load is reduced.
