Harken Runner Blocks

(12 products)

Black Magic(R) Air Runners(R) are strong, lightweight blocks with extremely free-rolling sheaves. Blocks feature Torlon(R) 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(R) to protect your blocks, deck, and crew.
