Harken 57 mm Zircon Triple Block Lewmar Evo Self-Tailing Winch Manufacturer part #: 32-77Harken 57 mm Zircon Triple Block 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.
