Harken 2670 75mm 3" Single Swivel Carbo Airblock Ratchet DN Iceboat Block
HARKEN 2670
Single Carbo Ratchet Block - 75mm
Carbo Ratchets allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing.
Nylon-resin side plates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Machined aluminum sheaves are Hard Lube-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.
75mm
The 75mm switchable ratchets 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 to allow double holding power in heavy air and to ensure a free-running mainsheet in light air. The 75mm holding power is up to 15:1. (Holding Power with 180° wrap at 50 Lbs.)
