Harken's® Carbo ratchet blocks represent a new line of on/off switchable ratchets, available in multiple configurations, for all ratchet applications on dinghies and keelboats.

They feature lightweight nylon resin sideplates, densely packed with long glass-fibers, to replace stainless steel reinforcing straps. The fibers align with block contours for superior strength.
