The Grade 120 Self-Locking Hook with Shortening Clutch is an advanced, high-performance lifting component that seamlessly integrates automatic safety locking with rapid chain length adjustment in a single unit.

• Automatic Safety Locking: Features a precision-engineered latch that closes and securely locks automatically as soon as a load is applied, drastically reducing the risk of accidental detachment during complex lifts.
• Integrated Shortening Clutch: Built-in chain adjuster (clutch) allows operators to make quick, tool-free adjustments to the chain leg length, ensuring perfectly balanced loads in variable rigging scenarios.
• Ultimate Strength-to-Weight Ratio: Forged from ultra-high-strength Grade 120 alloy steel, offering up to 50% higher Working Load Limits (WLL) compared to Grade 80 equivalents of the same size.
• Streamlined Rigging Setup: Combines two critical lifting functions into one compact device, reducing the number of components needed on the sling assembly and increasing overall operational efficiency.
