Jaycar Light Duty Large Trailer Coupling Lock

Same problem as the compact one, but your coupling's a bit bigger and you want something that wraps around it properly. This is that lock.

It connects directly to your trailer coupling and stops a tow ball from engaging. Light-duty build, larger footprint than the compact version – so if your hitch is on the wider side, this is the one that seats correctly without fighting you. No electronics, no battery anxiety. You lock it, you walk, you come back to your trailer.

Simple, mechanical, done. Add to cart and stop leaving that rig exposed in a public car park

• Connects directly to your trailer coupling, preventing tow ball attachment
• Large light-duty design for wider couplings
• Mechanical lock – no batteries or charging required
• Keeps caravan or trailer secure while your tow vehicle is elsewhere
