Jaycar Heavy Duty Large Trailer Coupling Lock

You've got a bigger rig out there and the light-duty locks just don't feel right on it. This one's built heavier, sized larger, and does the same job: sits on your coupling and stops a tow ball from connecting.

Heavy-duty construction for people who want that extra physical barrier without reaching for an alarmed lock. No batteries to track down, no siren to test. You lock it on, you drive off, you come back to your trailer. Period.

If your coupling's on the larger side and you want a lock that matches the build of the rig, this is the one. Add to cart

• Connects directly to your trailer coupling, preventing tow ball attachment
• Heavy-duty large construction for bigger couplings and rigs
• Mechanical lock – no batteries, no electronics, nothing to maintain
• Keeps caravan or trailer secure while your tow vehicle is elsewhere
