Harken 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.

Efficienza a basso attrito

La gabbia centrale mantiene separati e paralleli i cuscinetti a rulli Torlon® per ridurre l'attrito. I cuscinetti a sfere captivi Delrin® sopportano i carichi laterali.
