Harken 40mm Carbo Air Pivoting Lead Block, Cam

The Harken 40mm Carbo Air Pivoting Lead Block with Aluminum Cam-Matic Cleat is built for halyard controls on larger keelboats and doubles as a "headknocker" on dinghies and beachcats for sheeting directly off the boom.

Hole spacing and rivet size match Harken's Classic models, so upgrading an existing install doesn't call for new mounting holes. The cam reverses to allow either up or down cleating, whichever the specific control line calls for.

It can also be used as a becket block when needed, adding flexibility beyond a single fixed role, rated to a 300-lb maximum working load. Shop more sailing hardware.
