13mm x 13.5t G80 Truck Safety Chain Holder
13mm x 13.5t G80 truck safety chain holders use a 4140 high-tensile pin on vehicles that weigh 13.5 tonnes.
Chain Holder Installation Instructions:
- Weld the safety chain holder to the tow bar.
- Weld safety chain holders directly to the trailer chassis rail as close to the coupling as possible.
- Aluminium Trailers: Weld the chain holder to a plate and bolt it to the trailer via 4 x high-tensile bolts.
- The triangle tag is a safety feature that prevents the 4140 pin from falling out of the holder.
Testing G80 Safety Chain Holders
Road safety starts with product safety and product testing.
The 200t press above is set up to destroy the safety chain holder to its breaking point and record the data.
Welding plays a crucial role in safety. Incorrect or unprofessional welding causes dangerous situations.

- Every truck with a tow bar that tows a trailer over 3.5t must have a pair of safety chain holders attached. The holder has a 4140-grade pin.
- Mount the chain holders on either side, as close as possible to the tow bar coupling.
- The attachment must withstand static forces during towing and, in particular, resist cracks or breaks.

FAQ & Safety Guide: 13mm x 13.5t G80 Truck Safety Chain Holder
What You SHOULD Do (Do’s)
- Do match chain and holder ratings: Pair this holder with a compatible 13mm Grade 80 (G80) transport or safety chain.
- Do use a certified welder: Always have a qualified professional weld this heavy-duty holder to your truck chassis or trailer drawbar to ensure structural integrity.
- Do verify the load limits: Confirm that your total aggregate trailer mass (ATM) does not exceed the holder’s maximum 13.5-tonne rating.
- Do preheat before welding: Follow proper welding procedures for high-tensile steel castings, which typically require preheating to prevent weld cracking.
- Do perform regular inspections: Periodically check the holder and surrounding welds for distortion, cracks, stretching, or severe corrosion.
What You Should NOT Do (Don’ts)
- Don’t exceed the 13.5t capacity: Never use this component for heavy-duty recovery or towing setups that surpass its rated capacity.
- Don’t use with smaller/larger chain: Avoid using chains smaller than 13mm (which can slip) or larger chains that will not seat correctly in the slot.
- Don’t weld over the pin mechanism: Keep weld splatter and heat away from the locking pin area to ensure the chain remains quickly removable.
- Don’t modify or grind the holder: Never cut, alter, or heavily grind down the holder body, as this severely compromises its G80 strength rating.
- Don’t use for overhead lifting: Truck safety chain holders are rated only for towing and tie-down applications, not lifting.
