Harken 6272 60mm Element Triple Block with Swivel and Locking Shackle

The Harken 6272 is a 60 mm aluminum Element Triple Block with swivel and locking shackle, engineered for sailors who demand reliable Harken performance at an accessible price point. Three sheaves in a single compact body make this block ideal for mainsheets, vangs, multi-purchase tackle systems, and other high-load running rigging applications.

The Element series was built around a simple principle: strip away everything that doesn't directly contribute to durability or strength. The result is a block that pairs forged aluminum sideplates shaped with compound curves for structural integrity with a proven journal bearing system—delivering smooth, dependable line movement under load.

Key Features:

• Forged aluminum sideplates with compound curves for maximum strength-to-weight ratio
• Hardcoat-anodized sideplates resist corrosion in harsh marine environments
• Tough composite bearing sheave provides corrosion resistance and long service life
• Swivel attachment allows the block to rotate freely, reducing line twist
• Locking shackle provides secure, tool-free attachment and easy removal
• Triple-sheave design suited for multi-purchase tackle and high-load applications
