Harken® ball bearing cam cleats hold lines securely and release instantly for easy, precise trimming. Multiple rows of high-load ball bearings reduce friction so cams open easily for snap-down, rather than draw-through cleating. The cam horns and smooth V-shape guide the line for easy entry. This allows precise sail control without having to readjust the cleated line. Lightweight fiber-reinforced Carbo-Cams® are for racing where weight is critical, or where adjustments are less frequent. UV-stabilized with carbon-black additive for maximum protection.
