HARKEN 125 mm Aluminum Black Magic Double Footblock, 3258

Use footblocks to redirect lines on the deck. Footblocks with lock-offs temporarily secure sheets. Either metric or imperial flathead fasteners may be used for mounting and are not exposed. Sideplates and sheaves are Hard Lube-anodized for maximum UV protection and a smooth surface. The center cage keeps Torlon® roller bearings separated and parallel to reduce friction; the block carries some of the highest loads imposed by running rigging. Torlon is a registered trademark of Solvay Advanced Polymers L.L.C.

Note: Special Order Only

• Redesigned with a sleek look the Black Magic Air blocks have the same unique, performance-packed engineering as ever.
