Redesigned with a sleek look the Black Magic Air blocks has their same unique, performance-packed engineering as ever.

Black Magic Air Runners are strong, lightweight blocks with extremely free-rolling 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. Foam padded Block Socks easily install over Air Runner blocks to protect your blocks, deck, and crew.
