Grade 100 Clevis C Hook CCK Type

No.505011

The Grade 100 Clevis C Hook (CCK Type) is a compact, high-strength hook designed for attaching Grade 100 chain sling legs directly to structural members, beams, or load points in tight spaces.

  • C-Shape Profile: The open C-shaped body allows for quick engagement and disengagement from beams or flanges without needing to thread the chain through.
  • Direct Clevis Attachment: The integrated clevis pin provides a fast, secure connection directly to Grade 100 chain links without extra hardware.
  • Grade 100 Strength: Forged from premium alloy steel, offering approximately 25% greater WLL than an equivalent Grade 80 hook for the same chain size.
  • Available Sizes: Offered for chain sizes 7/8mm (WLL 2.5t) and 10mm (WLL 4t), suitable for light to medium duty lifting assemblies.

Grade 100 Clevis C-Hook / Foundry Hook - CCK Type

Extra-Wide Throat for Large Loads
Grade 100 Alloy Steel Wide Throat Clevis Connection Latch-Free
Grade 100 Clevis C Hook CCK Type

*Wide throat opening for large pipes and trunnions

Product Features

  • Extra-Wide Throat: Designed with a significantly larger throat opening than standard sling hooks. This allows the hook to fit over large diameter pipes, trunnions, bars, or thick plates that standard hooks cannot accommodate.
  • Foundry & Industrial Application: Originally designed for foundry applications where heat might damage latch springs, or where operators cannot manually open a latch due to distance or hazard.
  • Direct Clevis Connection: Features an integrated clevis pin for direct attachment to Grade 100 Chain. This creates a strong, compact assembly without the need for extra connecting links.
  • Grade 100 Strength: Offers 25% higher lifting capacity than Grade 80 equivalents, making it lighter and easier to handle for heavy-duty tasks.
  • Safety Note: This is a Non-Locking hook (No Safety Latch). It relies on gravity and load tension to stay engaged. Care must be taken to prevent slack lines that could cause accidental disengagement.

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.

Identification & Markings

Every Grade 100 component must be clearly marked with:

  • Grade: G100 or 10
  • Manufacturer's Mark
  • Size or WLL
  • Traceability Code (Batch / Heat Number)
⚠️ 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.
