Harken Carbo Pivot Lead Block With Aluminium Cam - 29mm 

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. Can be used as becket block.
