Harken 29mm Zircon Double Block with BKT

Product Description

The Harken 29mm Zircon Double Block with Becket is a high - performance sailing block, designed for lightweight strength and durability. Constructed with Harken’s advanced materials, the block features a 29 mm  sheave, made from UV - stable composite, reducing friction and wear for smooth line handling.

The double block configuration allows for versatile rigging solutions, while the integrated Becket adds functionality for creating terminating lines. Its compact, lightweight design makes it ideal for dinghies, small keelboats, or applications where efficiency and weight savings are critical. 

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. With Harken’s signature engineering and precision manufacturing, this block ensures reliable performance under load, making it a trusted choice for sailors demanding efficiency and strength on the water.
