Harken 29mm Zircon Triple Block

Product Description

The Harken 29mm Zircon Triple Block is a robust and lightweight sailing block engineered for high performance in demanding conditions. Crafted with cutting edge Zytel composite materials, it ensures durability and resistance to wear, while keeping weight to a minimum.

This triple block features three sheaves with a 29 mm diameter, designed to handle small - diameter, high - strength lines for efficient line management. The block incorporates ball bearings, made from Delrin, ensuring smooth operation and a reduction of friction under load. With a sleek design, it can handle working loads up to 450kg (992 lbs) and accommodates lines up to 8mm in diameter, making it ideal for various applications.

Zircon blocks help trimmers match sail shapes to new conditions immediately. Its compact size and innovative engineering make it a trusted choice for sailors seeking reliability and efficiency in their rigging setup. 

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.
