Harken 40mm Zircon Triple Block with BKT

Product Description

The Harken 40mm Zircon Triple Block with Becket is a high - performance pulley, designed for demanding marine environments. Featuring a lightweight, durable construction, it incorporates Zincon, a specialised surface treatment that offers exceptional corrosion resistance, making it ideal for use in both saltwater and freshwater conditions. 

The triple block design provides increased mechanical advantage, allowing for smoother, more efficient line handling. Zircon blocks help trimmers match sail shapes to new conditions immediately. The becket allows for easy attachment of a second line, enhancing versatility.

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.

This block is an excellent choice for various applications and line control on small - medium boats. Its design ensures strength, reliability, and ease of use, while minimising friction and wear.
