Grade 80 Hooks
G80 Eye Shorterning Grab Hook
A drop-forged alloy steel G80 eye shortening grab hook with a safety pin, designed to shorten chain slings and allow back-hooking. It maintains full working load limit when used with a safety pin. Available from 6-8 to 22-8 size, powder coated for corrosion resistance, and used in lifting gear applications. The safety pin prevents accidental chain release without reducing capacity.

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 G80 hook without safety pin | The grab hook with safety pin prevents accidental release but adds a small weight and requires pin inspection before use |
| Chain link with welded end | The grab hook allows for quick adjustment and re-use without cutting, while a welded link is permanent and not reusable |
| Screw pin hook | The safety pin on this grab hook is more secure under vibration and does not require frequent tightening compared to a screw pin |
| Soft link or synthetic sling | The steel grab hook handles abrasion and high temperatures better than synthetic materials, but is heavier and less flexible |
Use Guide
How To Use And Inspect G80 Eye Shorterning Grab Hook
- Always engage the safety pin before applying load to prevent accidental chain release
- Verify the safety pin is fully seated and the cotter or locking mechanism is secure
- Match the stamped working load limit to the actual load, not the chain or winch rating
- Inspect the hook body, pin, and safety mechanism for deformation or wear before each use
- Do not use if the powder coating is chipped or the safety pin is damaged
- Retire the hook if the eye shows deformation, the pin does not seat properly, or the marking is illegible

Answers
G80 Eye Shorterning Grab Hook FAQ
Can the safety pin be removed for use with a different pin?
No. The safety pin is designed to prevent accidental release and must remain in place during use. Removing it reduces safety and is not recommended.
Is the safety pin included with the hook?
Yes. The G80 Eye Shortening Grab Hook comes with a safety pin as standard, which prevents accidental chain release without derating the capacity.
What is the design factor for this hook?
A standard 4:1 design factor is used, so the minimum breaking load is four times the stated safe working load.
Can you provide a Material Test Certificate?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with each order on request.
What sizes are available?
Sizes range from 6-8 to 22-8. The full size table includes WLL, B.L., and dimensions E, D, H, R, L with tolerances.
How are the hooks packed for export?
Packed in cartons, then palletized. We can configure carton count and pallet pattern to suit your warehouse or retail pack.
Can you custom stamp our brand and tonnage?
Yes. Custom tonnage stamping, private label marking, and OEM packing are standard options.
