login to saveProduct Description
The Harken 57 mm Zircon Triple Block with Becket is a high - performance sailing block designed for demanding applications, combining durability and efficiency. Engineered with Harken’s renowned craftsmanship, this triple block is constructed from robust materials that resists corrosion in harsh marine environments.
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 with Becket is an essential addition to any performance sailing setup, delivering reliability, efficiency, and ease of use in critical sailing applications.
