Harken 57mm Swivel Carbo Fiddle Ratchet Block w/ Becket

Harken's Carbo Fiddle Blocks feature high-load ball bearings with fitted races for low-friction operation. Low-friction Carbo AirBlocks® are lightweight, strong, reliable—and affordable. Companions to the popular Harken® Black Magic® line, these small, compact blocks have very high working loads for safe, easy trimming.

The 57mm switchable ratchets provide precise on/off control with accessible, easy to operate on/off switches on both sides of the block.  An excellent choice for vangs, cunninghams, outhauls and mainsheet fine-tune.
