The entire line of Black Magic® AirBlocks® has been redesigned with a sleek new look. Their unique, performance-packed engineering remains exactly the same. Black Magic® Air Runners® are strong, lightweight blocks with extremely free-rolling sheaves. Blocks feature Torlon® roller bearings in a center cage for strength. Heads are offered with parallel/perpendicular shackles. Tangs attach turnbuckles, toggles, and other fittings. No tools required for installation.
