The entire line of Harken 57 mm Black Magic Airblocks has been redesigned with a sleek new look. Their unique, performance-packaged engineering remains exactly the same.

Used on offshore boats, these strong, lightweight locks 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 sideload ball bearings. Dissimilar metals are isolated to minimize corrosion.

Low-load blocks use Torlon rollers and 316 stainless steel shackles. Standard blocks have 17-APH stainless headposts.

Like all Harken 57 mm Black Magic AirBlocks, the three-way head swivels/locks in front/side positions. Blocks are easily disassembled with a single hex wrench.

The 3214 soft-attachment Loop block has a removable dead-end post for attachment to a padeye. Lashings can also be used.
