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 Hardkote anodized for strength and corrosion resistance.

Eight facets hold line securely.

Ball bearings, sheave and side plates are UV-stabilized with carbon black for maximum protection.

The 57mm switchable ratchets provide precise on/off control with accessible, easy-to-operate on/off switches on both sides of the block.
