Upgrade your existing kicker system to the latest XD specification with this ready made assembly using Harken's T2 Soft-Attach Carbo 18mm double block, Dyneema SK78 primary line and Dyneema cored secondary line. The new light weight 18mm Harken block is both lighter and stronger than the older 16mm design, and the Dyneema primary and Dyneema cored secondary lines ensure minimum stretch. 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/Polyester covered Robline Dinghy Control (available in Red/White, Yellow/White, Navy Blue/White, Purple/White, Green/White or Neon Orange/White). Includes plastic handle or a longer length secondary if you prefer a braided chain type handle.
