Harken 29mm Clew Block is a compact, lightweight solution designed for efficient sheeting and control on performance sails. Part of the trusted Carbo Air range, this block delivers smooth, low-friction operation with excellent strength in a streamlined, low-profile design.
Specifically suited for clew attachment, this block helps optimise sail shape and control by reducing friction and improving line efficiency. Its lightweight construction minimises added weight at the sail, enhancing overall performance, particularly on dinghies and high-performance small boats.
Built with durable, fibre-reinforced sideplates and low-friction ball bearings, the 29mm Clew Block provides reliable performance under load, making it ideal for jib sheets, control lines and other sail handling systems.
