Safety Chain D-Shackle for Tow Bars | Maximum 4.0t ATM

All trailers in Australia, including caravans and campers, must be connected to the tow vehicle through a rated chain.

It’s common to use D-shackles as connectors between the safety chain and the tow bar. D-shackles are cheap, simple to attach/detach and provide a secure connection, making them an easy choice for trailer and caravan owners.

Some find the 4.0t ATM D-Shackle pin’s size difficult to remove, in which case this 8mm chain hook set may be a more convenient option.

Regardless, D-Shackles are simple and get the job done!
