The Harken Black Magic Air Blocks have been redesigned with a sleek new look. Their unique, performance packed engineering remains exactly the same.

Used on offshore boats, these strong, lightweight blocks feature free-rolling, high load Torlon® roller bearings for a high strength-to-weight ratio and reduced wear. Rollers are housed in a center cage and stay parallel for low-friction efficiency. Sculpted hardcoat-anodized aluminum sideplates protect sideload ball bearings. Dissimilar metals are isolated to minimize corrosion.

The soft attachment Loop block has a removable deadend post for attachment to a padeye. Lashings can also be used. Soft Loop attaches securely through sheave center.*
