The entire line of Black Magic® AirBlocks® has 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 Torlon® roller bearings for strength and reduced wear. Rollers are housed in a center cage and stay parallel for low friction efficiency. Sculpted hardcoat-anodized aluminum sideplates protect side load ball bearings. Dissimilar metals are isolated to minimize corrosion. Like all AirBlocks®, the three-way head swivels/locks in front/side positions. Blocks have 17-4PH stainless headposts and are easily disassembled with a single Allen wrench.
