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
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
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.
