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.
