Harken Black Magic AirBlocks
The entire line of Harken 150 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.
Like all Harken 150 mm Black Magic AirBlocks , the three-way head swivels/locks in front/side positions. Blocks are easily disassembled with a single hex wrench.
