Harken 40mm Single Swivel Carbo Ratchet BlockSheave dia. - 1 9/16in - 40mm
Carbo Ratchets allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing. 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. Free-rolling ball bearings, sheave and sideplates UV stabilized with black additive for maximum protection.
The 40MM ratchet are ideal for jib sheets and spinnakers where size and weight are critical. This block has an on/off switch for ratchet mode.
