Black Magic AirBlocks

STRONG, LIGHTWEIGHT, AND FREE ROLLING

Weedend cruiser? Around-the-world racer? You'll want Black Magic AirBlocks aboard. With high strength-to-weight ratios and free-rolling high-load roller bearings, these versatile blocks are the workhorses of the Harken line. Use for sail controls that see lots of action including mainsheet, runner, halyard, and spinnaker systems.

AirBlocks are very easy to clean and service. They have few parts and no loose balls or rollers to misplace. Unlike blocks that are riveted together, three fasteners allow quick disassembly for service.
