Product information
Zircon Blokks 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 Blokk Harken has ever made.
Zircon Blokks are available in 40- and 57-mm sheaves in Single and double Blokks, with or without beckets.
