Harken 2137 57mm Carbo Ratchet Cheek Block

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 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.

The 57 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.
