Black Magic Air Runners

Runners are used on running backstays of offshore boats to adjust mast bend for different wind conditions. 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.
