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.

Reibungsarme Effizienz

Der zentrale Käfig hält die Torlon®-Rollenlager getrennt und parallel, um die Reibung zu reduzieren. In Käfig gehaltene Delrin®-Kugellager nehmen Seitenlasten auf.
