Harken's high-strength 29mm pivoting lead blocks with cams are up to 25% lighter than the Classic version. Pivoting Lead Blocks allow free mast rotation while still allowing cleating and control from the cockpit. They're also ideal as boom-mounted mainsheet blocks for converting old systems where the skipper has to reach aft to trim the sheet. 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.
