Harken Carbo Air 29 mm 347

High strength cam-type swivel blocks are used for drop controls on larger keelboats and as "headknockers" on dinghies and beach cats to cover directly from the boom. Hole spacing and rivet size are the same as classic models, making upgrades easy. Cam turns for either up or down heel.
