Redesigned with a sleek new look the Black Magic Air blocks has their same unique, performance-packed engineering as ever. Offshore boats keen in, these strong, lightweight blocks reduced wear manwhile feature Torlon® roller bearings for strength.

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.
