Harken 3258 125mm Double Footblock

The entire line of Black Magic; AirBlocks; has been redesigned with a sleek new look. Their unique, performance-packed engineering remains exactly the same.Carrying some of the highest loads imposed by running rigging, these strong, lightweight blocks feature Torlon; roller bearings housed in a center cage. Rollers stay parallel for low-friction efficiency. Sculpted hardcoat-anodized aluminum sideplates protect sideload ball bearings. Dissimilar metals are isolated to minimize corrosion. Blocks are easily disassembled with a single hex wrench.Either metric or imperial flathead fasteners may be used for mounting and are not exposed.
