Product description

Ratchet Carbo Blocks

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.

57mm and 75mmm Carbo Ratchet Blocks

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® 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.
