Upgrade your existing kicker system with this easy to fit, ready made assembly using the new Ronstan 20mm high load double block bundled with the new Ronstan high-load top block.   

The 4mm secondary control line rope is SK78 Dyneema cored, Technora/Polyester covered Robline Dinghy Polytech.  Includes plastic handle or a longer length secondary if you prefer a braided chain type handle. 

NOTE: As the optimum line lengths are different for Harken and Ronstan lower assemblies, select which lower assembly this should be optimised for.
