Upgrade your existing kicker system with this ready made assembly using the new Ronstan 20mm high load double block. Choose from a range of primary line colours (white and light grey (good for marking calibrations with a pen), very dark grey, or if you want a colour coded system - red, yellow, or blue). 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 - by default the primary comes with a loop on the end to luggage tag onto the popular Harken 466 top block. If you want to tie or splice it onto a high load top block add the 'System Option- free end on primary line for High Load Block' to your order.
