Zircon blocks help trimmers match sail shapes to new conditions immediately. At the core of the Zircon performance are industrial ceramic ball bearings mounted inside caged races. The cages keep these bearings separated so they don't bunch, touch, and stop each other. The result is the most efficient small boat block Harken has ever made. Zircon blocks are available in 40mm and 57mm sheaves in single and double blocks, with or without beckets.
