HARKEN BLACK MAGIC BLOCKS

Harken Black Magic blocks are lightweight and 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.

Harken Black Magic high-load 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.
