Product Description

Harken 57mm Aluminum 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.
