Grade 80 Hooks
G80 Clevis Shortening Grab Hook
A drop-forged alloy steel clevis shortening grab hook in Grade 80, designed to adjust the length of chain slings by shortening or lengthening the connection point. It features a grab mechanism with a safety pin to prevent accidental release while maintaining full capacity. Powder coated finish for corrosion resistance. Used in lifting gear applications where precise chain length adjustment is required. Sizes range from 6-8 to 22-8 with safe working loads from 0.25T to 15T.

Key Benefits
What G80 Clevis Shortening Grab Hook Gives You
- Adjusts chain sling length on the fly without removing links or reassembling the sling
- Grab hook mechanism holds the chain securely during lifting and transport
- Safety pin prevents accidental chain release while maintaining full working load limit
- Drop-forged alloy steel body with quench and temper heat treatment for high strength and impact resistance
- Powder coated finish resists rust and wear in harsh industrial and marine environments
- Standard 4:1 design factor ensures consistent safety margin across all sizes
- Compact design reduces bulk compared to multiple shackle and link setups
Application Scenarios
Where G80 Clevis Shortening Grab Hook Is Used
- Adjusting chain sling length on-site during crane or hoist rigging setup

How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Standard chain link with shackle | The clevis shortening grab hook allows dynamic length adjustment without disassembly, while a shackle and link require removal and reassembly |
| Screw pin shackle | The safety pin in this hook prevents accidental release and does not require tightening during use, unlike a screw pin which can loosen under vibration |
| Rigid clevis hook | The grab mechanism provides a secure grip on the chain, reducing slippage during lifting, while a rigid hook relies on friction and may slip under dynamic load |
| Adjustable chain connector with nuts | The grab hook is faster to adjust and does not require tools, while a threaded connector is slower and more prone to thread damage |
Use Guide
How To Use And Inspect G80 Clevis Shortening Grab Hook
- Match the hook size and chain diameter to ensure compatibility before attaching
- Never exceed the stamped safe working load limit for the size used
- Ensure the safety pin is fully engaged and the grab hook is securely holding the chain
- Inspect the powder coat for damage before each use; replace if coating is chipped or worn
- Do not use for overhead lifting; intended only for chain sling shortening and adjustment
- Retire the hook if the body shows deformation, the safety pin fails to hold, or the marking is illegible

Answers
G80 Clevis Shortening Grab Hook FAQ
Is this hook rated for overhead lifting?
No. It is designed for chain sling shortening and adjustment, not for overhead lifting. Do not use in overhead lifting applications.
What is the safety factor?
A standard 4:1 design factor is used, so the minimum breaking load is four times the safe working load.
Can the safety pin be replaced or modified?
The safety pin is designed to be non-removable during use. Replacement is not recommended unless specified in a custom order.
What finishes are available?
Standard finish is powder coated. Custom finishes include zinc plating, electrophoretic black, and powder coating in other colors upon request.
Can you provide a Material Test Certificate?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with the order on request.
How are the hooks packed for export?
Packed in cartons, then palletized. We can configure carton count and pallet pattern to match your warehouse or retail pack.
What sizes are available?
Sizes range from 6-8 to 22-8. Safe working loads range from 0.25T to 15T. Full dimensions and weights are listed in the size table.
