Product Description

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. Integral sideplate bails and recessed cotter key help produce a smooth design that won't snag lifelines.
