Description
Harken 29-75mm Carbo Triple Becket Blocks & Cleat – High-strength pivoting lead blocks with cams are used for halyard controls on larger keelboats and as “head-knockers” 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.
