Harken 100 mm Air Blocks
The entire line of Harken 100 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 100 mm Black Magic AirBlocks, the three-way
head swivels/locks in front/side positions. Blocks are easily disassembled
with a single hex wrench.
The 3245 soft-attachment Loop block has a removable dead-end post for attachment
to a padeye. Lashings can also be used.
