Harken Air Runner Blocks

Harken Air Runner Blocks
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.
