Use XCS on yachts that require a higher safe working load and a more advanced release mechanism than the XAS. The XCS also features further durability due to its metal sides and is therefore good for mast mounted applications where a knock from a spinnaker pole could be a common occurrence. Use the XCS0608/1 version on applications that are specific to 5/16" (8mm) lines or upgrade your current model with our CAM-0608 to ensure the best possible holding solution on smaller diameters Available in white, black, or silver finish Small diameter clutches optimized for 5/16" and strongly recommended for high strength line
