Harken 6273 60mm Aluminum Element Triple Block with Swivel and Becket

The Harken 6273 is a 60mm Aluminum Element Triple Block featuring a swivel and becket, purpose-built for sailors seeking Harken performance and engineering at an accessible price point. The Element series was designed around a core philosophy: strip away everything that doesn't contribute to strength or durability, delivering a capable, corrosion-resistant sailing block without compromise.

The sideplates are constructed from forged aluminum with compound curves, providing exceptional structural rigidity in a modern, low-profile form. A hardcoat-anodized finish on the sideplates delivers superior corrosion resistance for long-term use in harsh marine environments. The sheave uses a tough composite bearing that further resists corrosion while maintaining smooth, reliable line movement across its full load range.

The triple-sheave configuration, combined with the integrated swivel and becket, makes this block ideal for high-load running rigging applications such as mainsheets, halyards, and multi-purchase purchase systems aboard larger sailboats.
