      Product description

      Black Magic Air blocks are a top favorite of Big Boat performance racers and cruisers. These lightweight, free-running, powerful performers are used for sail controls that see lots of action: mainsheet, runner, halyard, and spinnaker systems.

      Sideplates and sheaves Hard Lube-anodized for maximum UV protection and a smooth surface.

      Center cage keeps Torlon® roller bearings separated and parallel to reduce friction.

      These strong, lightweight blocks feature free-rolling, high-load Torlon® roller bearings for a high strength-to-weight ratio. Use them for sail controls that see lots of action: mainsheet, runner, halyard, and spinnaker systems.

      Air blocks are easy to clean and service. They have few parts and no loose balls or rollers to misplace. Unlike blocks that are riveted, fasteners allow quick disassembly with a single hex wrench.

      Torlon is a registered trademark of Solvay Advanced Polymers.
