The Grade 100 Clevis Cradle Grab Hook (CGK Type) is a heavy-duty chain shortener engineered to quickly and safely adjust the length of multi-leg chain slings.
100% Capacity Retention: Features specialized supporting side lugs (cradle wings) that fully support the chain link, preventing distortion and allowing the lifting assembly to safely maintain 100% of its rated Working Load Limit.
Direct Chain Connection: The built-in clevis mechanism and load pin allow for fast, secure attachment directly to Grade 100 lifting chains without requiring extra coupling links.
Grade 100 Strength: Manufactured from premium alloy steel, offering 25% more lifting capacity than Grade 80 hooks, accommodating chain sizes from 6mm (1.4t WLL) to 32mm (40t WLL).
Safe Chain Shortening: The precisely engineered narrow throat securely grabs and holds the chain, making it highly effective for adjusting sling legs and back-hooking in demanding overhead lifts.
100% Load Capacity (Cradle Design): Unlike standard grab hooks that can crush chain links, the CGK Type features supportive "wings" (cradles) on the sides of the hook. This distributes the load evenly and allows the sling to be used at 100% of its Working Load Limit without reduction.
Grade 100 Performance: Forged from high-strength Grade 100 Alloy Steel. Offers 25% higher lifting capacity than Grade 80 hooks, making it ideal for heavy-duty shortening applications where weight saving is key.
Integrated Clevis: Features a built-in clevis pin for direct attachment to the chain leg. This creates a compact shortening station without the need for additional connecting links.
Rapid Adjustment: The open throat design allows operators to quickly grab a chain link to adjust leg length. (Note: For locking security, consider our Locking Shortening Clutch).
Deep Chain Pocket: The precise throat geometry ensures the chain is held securely in the vertical position.
Standard: Compliant with ASTM A952 and EN 1677-1.

Load Capacity Impact
Cradle Grab (CGK) (This Product)
Winged / Cradle
100% Capacity. Side wings support the link. No reduction in WLL is required. Safe for full loads.
Standard Grab (Non-Cradle)
No Wings
Reduced Capacity (-20%). Lack of support bends the link. You MUST reduce the sling's WLL by 20% for safety.

Grade 100 Sling Components
Grade 100 Sling Components are high-strength alloy steel lifting accessories designed for heavy-duty lifting applications. Compared with Grade 80, Grade 100 offers higher working load limits (WLL) at the same size, or the same WLL with a smaller, lighter component.
What Does "Grade 100" Mean?
High-Strength Alloy: Heat-treated, quenched, and tempered steel.
Increased Capacity: Typically 25% higher WLL than Grade 80.
Safety Factor: Minimum breaking force ≈ 4 × WLL.
Standards: EN 818-4 / EN 818-6, ASTM equivalents.

⚠️ Safety & Compatibility Warning
❌ NEVER mix Grade 100 with Grade 80 components in the same sling assembly.
✅ Use only Grade 100 chain + Grade 100 fittings together.
Regularly inspect for wear (>10%), cracks, deformation, heat damage, or corrosion.
