The standard setup is to fit the hook kit to the vehicle towbar anchor point, then connect your trailer safety chain to the hook.

• Kits are designed to connect safety chains to the towbar.
• Check that your towbar anchor points can accept the hook size.
• Light Trailer kit requires an 11mm hole.
• Heavy Trailer kit requires a 13mm hole.

Important: Do not assume every towbar anchor point will accept the connector size without checking.

Some customers prefer to fit the certified hook to the trailer safety chain, then hook back onto the vehicle towbar anchor point.

For this setup, you will need additional chain connectors to attach the certified hook assembly to the trailer safety chain.

Important: This accessory setup is only required if you want the hook fitted to the trailer chain.

If your trailer ATM is above 3,500kg and it uses short link lifting chain, the hook may not seat directly on the chain.

For short link lifting chain, match the Omega Link size to the chain size: use 10mm Omega Links with 10mm chain and 13mm Omega Links with 13mm chain. Use 2 Omega Links, one per safety chain.

The Omega Link creates a rated connection point between the lifting chain and certified hook without cutting or welding.

No. The hook ratings are not added together.

Each safety chain and each hook must be suitable for the trailer’s full ATM on its own. For example, a 2,000kg rated hook kit is suitable for trailers up to 2,000kg ATM. It does not become suitable for a 4,000kg trailer simply because two hooks are fitted.

For a 4,000kg trailer or caravan, the Heavy Trailer Kit is required.

Select the kit based on your trailer or caravan’s ATM, not the load you normally carry.

Light Trailer Kit: Suitable for trailers up to 2,000kg ATM.

Heavy Trailer Kit: Suitable for trailers up to 4,000kg ATM.

For a 3,500kg ATM caravan: select the Heavy Trailer Kit and confirm the chain, link opening, towbar hole and available clearance are compatible.

Your ATM can usually be found on the trailer compliance plate. When selecting towing safety components, always work from the trailer’s maximum rated ATM.

They are particularly useful for caravans, trailers, 4WDs, and setups where the chain connection point is hard to reach. They also provide the benefit of a dedicated towing product with Road Vehicle Regulator approval for the application.
