Harken Midrange Classic Hexaratchet Blocks grip loaded sheets, yet allow sailors to ease and trim quickly and with complete control. A switch on the side engages and disengages the ratchet mechanism.
Ratchets feature Hard Lube-anodized with PTFE-impregnated, eight sided sheaves machined from solid aluminum for strength and corrosion resistance. Free rolling Delrin® ball bearings, sheave, and sideplates are UV stabilized with carbon black for maximum protection. High strength stainless steel straps reinforce blocks.
