Harken Carbo 57mm Sixtuple Ratchet for 12:1 Cam Cleat

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.

Carbo Ratchets 10:1 allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing.
