The design belief was simply to develop the best Cam Cleat in the world. It had to be strong, lightweight, reliable, and come in a range of sizes to meet all cleating requirements.The result is the Ronstan C-Cleat, and when the influential consumer magazine Practical Sailor independently tested and compared cleats from all manufacturers they concluded that the C-Cleat was the world's best . These new cleats reach new levels of design excelence. Self cleaning, self lubricating, ribbed bearing system replaces traditional ball bearings which have flattened under load, or clogged with grit and salt. The ribbed bearing system results in less friction and quicker, more sensitive Cam response, which means easier cleating and uncleating even under load. Advanced, lightweight, corrision free composites replace heavy corrosion prone alloy and the fatigue free multi-coil spring system means spring breakdown is never again an issue. Over two years in development, the Cams of the C-Cleat are produced from lighweight, ultra rigid Carbon Fibre composites which are completly corrosion free, suffer virtually no tooth wear, are burn proof and non abrasive on rope. * Lightweight, carbon fibre cams providing superior performance, reduced wear * Outstanding grip on modern rope fibres * Unmatched strength to weight ratio * Quick response time * Ease of cleating and uncleating * Non corroding! * Self-cleaning, self, self-lubricating bearings **** Rope Capacity: 3-12mm 1/8-inch-1/2-inch * Max.
