Harken 57mm Zircon Triple Block

Product Description

The Harken 57 mm Zircon Triple Block is a high - performance sailing block, designed for durability, efficiency, and versatility in demanding conditions. Featuring three 57 mm sheaves, this block is built with lightweight, corrosion - resistant materials, ensuring optima performance in both saltwater and freshwater environments. 

The sheaves are equipped with low - friction ball bearings for smooth operation, reducing drag, maximising power transmission. The block is capable of handling high loads, making it ideal for various applications. The ergonomic design includes a robust attachment point and a compact footprint, ensuring easy integration into various rigging setups. The 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.

The Harken 57 mm Zircon Triple Block is part of Harken’s trusted lineup, renowned for its reliability and innovative engineering, making it a favourite among competitive and recreational sailors alike.
