Harken 3.00" Stbd Hexaratchet Cheek Block

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, 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.
