Harken 125mm Runner Block
Harken 125mm Runner Block
Runners are used on running backstays of offshore boats to adjust mast bend for different wind conditions. Integrated sideplate bails and recessed cotter key help produce a smooth design that won’t snag lifelines. Sideplates and sheaves Hard Lube-anodized for maximum UV protection and a smooth surface. Center cage keeps Torlon roller bearings separated and parallel to reduce friction. Torlon is a registered trademark of Solvay Advanced Polymers L.L.C.
