Black Magic® AirBlocks® - 57mm
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 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 side plates protect sideload ball bearings. Dissimilar metals are isolated to minimize corrosion. Like all Black Magic® AirBlocks®, the three-way head swivels/locks in front/side positions. Blocks are easily disassembled with a single hex wrench.
Standard blocks have 17-4 PH stainless head posts. Low-load blocks use Torlon® rollers and 316 stainless steel shackles. The 3214 soft-attachment Loop block has a removable dead-end post for attachment to a padeye. Lashings can also be used.
