Harken Black Magic Blocks

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.

AirBlocks® 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 dis-assembly with a single hex wrench.

Torlon® is a registered trademark of Solvay Advanced Polymers.
