- Black Magic Air blocks are a top favorite of Big Boat performance racers and cruisers
- Lightweight, free-running, powerful performers are used for sail controls that see lots of action: mainsheet, runner, halyard, and spinnaker systems
- Center cage keeps Torlon roller bearings separated and parallel to reduce friction
- Low-friction Carbo Air blocks are lightweight, strong, reliable—and affordable
- Companions to the popular Harken Black Magic block line, these small, compact blocks have very high working loads for safe, easy trimming
The entire line of black magic airblocks has been redesigned with a sleek new look. Their unique, performance-packed engineering remains exactly the same. Carrying some of the highest loads imposed by running rigging, these strong, lightweight blocks feature torlon; roller bearings housed in a center cage. Rollers stay parallel for low-friction efficiency. Sculpted hardcoat-anodized aluminum sideplates protect sideload ball bearings.
