This system comprises the Ronstan lower assembly, Allen XHL top block and Harken 2158 middle block, and spliced lines.   Complete ready rigged kicker assembly using our highest specification primary and secondary lines. The 4mm secondary control line Robline has a blended Technora®/Polyester cover for excellent durability and grip, and a Dyneema® SK78 core. These premium control lines, with the Technora in the cover provide greater longevity especially for the highly loaded kicker where the cleat causes wear, and excellent grip in the hands. Primary line is 3mm SK99 Dyneema in grey. Harken 2158 18mm double Carbo Block as the middle block, and the amazingly free-running Allen XHL top block with the new stronger design kicker key. Includes plastic handle or extra length line secondary line for a braided chain type handle. System options allow you to neatly take one purchase taken out of your kicker assembly and change the middle block type.  Allen XHL block is available in blue or black.
