Under Australian Transport Safety rules, not only trailer chains have to be made from high quality load tested chain, the shackle connecting it to your vehicle also needs to be a tested shackle.

It is quite easy to see if your shackle is tested. They usually have a yellow pin and the test results are stamped on the shackle. Fines of $150 and 3 demerit points have been incurred in Victoria.

Fortunately help is at hand! We stock PWB tested shackles that are made to AS2741 and comply with the regulations.

The standard also gives guidance on the USAGE of shackle

• Care should be taken that the shackle can freely articulate when it is in its secured position and attached to the chain, so that the shackle body can freely take the load along the axis of the centre line. (To ensure axial loading).
• Care should be taken to ensure that the shackle pins do not unscrew during use.
