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

The Harken 6273 is a 60 mm Aluminum Element Triple Block featuring a swivel and becket, engineered for sailors who demand reliable, high-load performance without compromise. Part of Harken's Element series, this triple sailing block delivers proven Harken design and engineering at an accessible price point — making it an ideal choice for mainsheet systems, halyards, and other high-load running rigging applications.

The Element series was purpose-built to strip away everything that doesn't contribute to strength or durability. The sideplates are forged aluminum with compound curves that maximize structural integrity while minimizing weight. A journal bearing design protects the sheave efficiently, and hardcoat anodizing on all sideplates provides excellent corrosion resistance for long-term use in harsh marine environments. The composite bearing sheave further resists corrosion for extended service life.

Key Features:

• Forged aluminum sideplates with compound curves for maximum strength-to-weight ratio
• Hardcoat-anodized sideplates resist corrosion in saltwater environments
• Tough composite bearing sheave for long service life and corrosion resistance
• Swivel attachment allows the block to orient freely under load
• Integrated becket for attaching a second line or block
• Journal bearing design optimizes load protection with minimal material

Specifications:

• Sheave Diameter: 60 mm (2-3/8 in)
