Description
Harken 29-75mm Carbo Air Triple Blocks with Cleat – High strength pivoting lead blocks with cams are used for halyard controls on larger keelboats and as “headknockers” on dinghies and beach cats for sheeting directly from the boom. Hole spacing and rivet size are the same as Classic models, making upgrades easy. Cam reverses for either up or down cleating.
