Carbo ratchet blocks allow sailors to hand-hold loaded lines and offer a 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 the line securely. Ball bearings, sheaves, and side plates are UV-stabilized with carbon black for maximum protection.
The 40 mm ratchets are ideal for jib sheets and spinnakers where size and weight are critical. The 2608, 2609, and 2614 have on/off switches; other 40 mm ratchets are always in ratchet mode.
