Harken Air Runner Black Magic Blocks
The entire line of Harken Air Runners Black Magic Blocks has been redesigned with a sleek new look. Their unique, performance-packed engineering remains exactly the same.
Harken Black Magic Air Runners are strong, lightweight blocks with extremely freerolling sheaves. Blocks feature Torlon roller bearings in a center cage for strength. Sideload bearing strips dampen rig vibration.
Integrated sideplate bails and recessed cotter key help produce a smooth design that won't snag lifelines.
Heads are offered with parallel/perpendicular shackles. Tangs attach turnbuckles, toggles, and other fittings. No tools required for installation.
Foam padded Block Socks easily install over Air Runners to protect your blocks, deck, and crew.
