SKU #: HK_HAR043

Availability: In stock

The Harken 57mm Hexaratchet Swivel Block grips loaded sheets, yet allows 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.

Use the 043 with the 019 or 050 single with becket on spinnaker and jib sheets where ratchets rotate in opposite directions and on/off switches face up.

Use for: Mainsheet systems, Jib sheets, Spinnaker sheets, Vangs
