Carbo ratchet blocks 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 hardcoat 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.
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.
57 mm & 75 mm
The 57 mm and 75 mm 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® block directly above for double holding power in heavy air and a free-running mainsheet when it’s light. The 75 mm provides up to 15:1 holding power; the 57 mm 10:1.
