    Product Description


    Harken Carbo Ratchets allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing. The Harken 57 mm Carbo Ratchet Blocks provide precise on/off control with accessible, easy-to-operate on/off switches on both sides of the block. For the ultimate system, mount a switchable ratchet in the cockpit and a boom-mounted Ratchamatic directly above for double holding power in heavy air and a free-running mainsheet when it's light. The Harken 57 mm Carbo Ratchet Block has a holding power of 10:1.

    Nylon resin sideplates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Machined aluminum sheaves are Hardkote anodized for strength and corrosion resistance. Eight facets hold line securely. Ball bearings, sheave, and sideplates are UV-stabilized with carbon black for maximum protection.

    Use For:
    • Main/jib/spinnaker sheets
    • Mainsheet fine-tune
    • Traveler controls
    • Genoa Leads
    • Foreguy
    • Vangs
