Harken Black Magic 57mm Footblock Single

Black Magic® AirBlocks®

The entire line of Black Magic® AirBlocks® has been redesigned with a sleek new look. Their unique, perfor- mance-packed engineering remains exactly the same.

57mm Footblocks:

Carrying some of the highest loads imposed by running rigging, these strong, lightVikt 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.
