Harken 40mm Pivoting Lead Block with Cam-Matic Cleat

Harken 40mm high strength pivoting lead blocks with cam cleats are used for halyard controls on larger keelboats and as “head knockers” on dinghies and beachcats for sheeting directly from the boom. They are also seen on catamaran masts for kite hoists and cleating.

Hole spacing and rivet size are the same as Classic models, making upgrades easy. The cam cleat can be reversed for either up or downward cleating.
