Harken 40mm Zircon Triple Block

Product Description

The  Harken 40mm Zircon Triple Block is a high - performance sailing block, designed for demanding applications where strength, efficiency, and durability are paramount. Featuring a robust, yet lightweight construction, this triple block is built with Harken’s renowned engineering excellence and premium materials. Its 40 mm sheaves are made from advanced composites to ensure smooth operation and resistance to wear, even under high loads. 

The block’s sideplates are reinforced for additional durability, while its compact design makes it ideal for complex line systems in competitive sailing scenarios. 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. Perfect for mainsheet systems, vang setups, or other multi - line configurations, the Harken 40mm Zircon Triple Block offers reliable performance under intense conditions.
