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.


Like all Air Blocks, the three-way head can be locked in either direction or can swivel freely to keep line from twisting.


Use for:


Sheets, Halyards, Running Backstays, Control Lines
