The Grade 100 Special Clevis Grab Hook with Safety Pin (SCG Type) is a high-performance shortening hook designed to quickly and securely adjust the leg length of overhead lifting chain slings.

Non-Destructive Cradling: Engineered with a specialized cradle that fully supports the chain link, allowing lengths to be adjusted without reducing the sling's Working Load Limit (WLL).
Safety Pin Security: Equipped with a built-in safety pin mechanism that securely traps the chain link inside the hook throat, preventing accidental disengagement when the chain goes slack.
Direct Clevis Mount: The clevis pin design allows for rapid, direct connection to the chain leg, eliminating the need for additional coupling hardware.
High-Strength Material: Manufactured from Grade 100 alloy steel for maximum durability, available for 8mm to 13mm chains with lifting capacities from 2.5 tons to 6.7 tons.

G-100 Special Clevis Grab Hook with Safety Pin SCG

*Safety pin keeps chain secure when slack

Product Features

Enhanced Safety (Locking Pin): Unlike standard open grab hooks, the SCG type features a sturdy Safety Pin across the hook throat. This keeps the chain link securely seated in the bowl, preventing it from vibrating out or falling off when the load is slack.
100% Working Load Limit: Features a Cradle (Winged) design that fully supports the chain link. This allows the hook to be used at 100% of the chain's rated capacity without the need for load reduction (unlike standard non-cradle hooks).
Direct Clevis Connection: Designed with an integral clevis pin for direct attachment to Grade 100 Chain, ensuring a compact and robust assembly.
Precise Shortening: Ideal for accurately adjusting the length of chain sling legs to level unbalanced loads.
Grade 100 Alloy: Forged from high-strength Grade 100 steel, offering 25% higher capacity than Grade 80 components.
Standard: Compliant with EN 1677-1 and ASTM A952.

Shortener Security: Standard vs. Locking

Model	Security Feature	Benefit
Locking Grab (SCG) (This Product)	Safety Pin	Won't Fall Out. Pin keeps the chain inside the hook even if the sling goes slack. Safer for overhead lifting.
Standard Grab Hook (Basic)	Open Throat	Quick Access. Easier to attach/detach, but chain can slip out if tension is lost.

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.
