40mm Harken Carbo Ratchet Block, Swivel, 471 Carbo-Cam, Becket

The Harken 40 mm Carbo ratchet block with swivel, 471 Carbo-Cam cleat and becket lets you hold a loaded sheet by hand and ease it under control. Harken recommends its 40 mm ratchets for jib and spinnaker sheets where low weight and small size are critical. With the integrated cam cleat you can cleat the line right at the block.
