Harken 40 mm Zircon Block with Becket JL Audio Side hand pockets for easyOverview 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 dont bunch, touch, and stop each other. The result is the most efficient small boat block Harken has ever made. Zircon blocks are available in 40 and 57 mm sheaves in single and double blocks, with or without beckets.
