Harken Air Runners Blocks

Runners are used on running backstays of offshore boats to adjust mast bend for different wind conditions. Foam-padded Block Socks easily install over Black Magic Air Runner blocks to protect blocks, deck, and crew.

Harken Black Magic Air Runners are strong, lightweight blocks with extremely freerolling sheaves. Blocks feature Torlon roller bearings in a center cage for strength. Sideload bearing strips dampen rig vibration.
