Harken 40mm Triple Zircon Block
The Harken Zircon blocks are the most efficient blocks on the market and this helps trimmers match sail shapes to new conditions immediately. The Zircon performance comes from industrial ceramic ball bearings that are mounted in a caged race. The cages keep the bearings separated so they don’t bunch, touch, and stop each other resulting in the most efficient small boat block Harken has ever made.
The 40mm Zircon efficiency is great for use on mainsheet systems to reduce friction and increase feeling. Feel any small variation in the breeze.
