Carbo AirBlock® line. This new ratchets 57mm and is useful for all ratchet applications on dinghies and keelboats.

Ratchets feature lightweight Nylon resin sideplates densely packed with long glass fibers to replace stainless steel reinforcing straps. Fibers align with block contours for strength.

”The 57 and 75 mm Carbo Ratchets are a great addition,” said Chuck Lob , senior engineer for standard products. “Like Harken’s 40 mm Carbo Ratchet, the new 57 mm and 75 mm ratchets are perfect for hand holding loaded lines and for controlled release. Harken has been the world’s leader with the largest ratchet offering. This product line illustrates our continued commitment to this leadership.”

The 57 mm ratchet provides sailors with up to 10:1 additional holding power. The 75 mm 15:1. Both ratchets feature accessible and easy-to-operate on/off switches (found in the center airhole) on both sides of the block. Machined Hardkote-anodized aluminum sheaves have eight facets to hold line securely.
