Grade 100 Master Link with Integrated Shortening Hook, MLS type

No.505028

The Grade 100 Master Link with Integrated Shortening Hook (MLS Type) is a streamlined top rigging component designed specifically for 1-leg chain sling applications.

  • Fully Integrated Design: Combines a solid master link with a single built-in eye grab hook, completely eliminating the need for separate connecting hardware and reducing sling weight.
  • Dual-Purpose Hook: The integrated grab hook functions simultaneously as a direct chain connector and an efficient shortening hook for quick length adjustments.
  • Grade 100 Strength: Forged from premium alloy steel, offering a 4:1 safety factor and up to 25% higher lifting capacity than standard Grade 80 equivalents.
  • Industrial Durability: Manufactured to meet EN 1677 standards, proof-tested to 2.5 times the Working Load Limit (WLL), and finished with a durable powder coating for corrosion resistance.

Product Features

  • Dedicated 1-Leg Design: The ideal top assembly for Single-Leg Chain Slings. It combines the master link and the shortening function into one sleek component.
  • Integrated Simplicity: Features a single shortening hook (grab hook) forged directly onto the master link. This design eliminates the need for a separate connecting link and grab hook, reducing the sling's weight and complexity.
  • Instant Adjustment: Allows the operator to quickly adjust the length of the single chain leg to suit varying lifting heights or to choke the load securely.
  • Maximized Headroom: By removing extra connecting hardware, the MLS link offers the shortest possible "headroom" (distance from the crane hook to the load), perfect for confined spaces.
  • Grade 100 Strength: Made from Grade 100 Alloy Steel, offering 25% greater capacity than Grade 80 components.
  • Full Link Support: The integrated hook pocket is designed to fully support the chain link, ensuring 100% WLL capacity without deformation.

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.
