Product Information
Full details
The Simply Auto Trailer Hitch Lock (THL001) is designed for owners of trailers, boats, and caravans who require a robust, reliable security solution for unattended equipment. Its primary benefit is the combination of a universal fit for 50mm couplers and a highly visible yellow finish that acts as an immediate visual deterrent to potential thieves. While it provides excellent protection against picking and prying, users should note that the unit must be properly maintained and kept clean to ensure the locking mechanism remains smooth over long-term outdoor use.

FAQs
What size coupler does this lock fit?
This lock is designed to fit most standard 50mm trailer, boat, and caravan couplers.
Does this lock prevent the trailer from being towed?
Yes, by blocking the ball hitch cavity, it prevents unauthorized vehicles from coupling with your trailer.
Is the finish weather-resistant?
Yes, it features a high-gloss, rustproof, and corrosion-resistant coating designed to withstand various weather conditions.
How many keys are included?
The package includes two keys.
Can I use this while the trailer is attached to my car?
No, this device is specifically designed for unattended, disconnected trailers.
What should I do if I lose both keys?
Since this is a high-security lock, we recommend keeping your spare key in a safe, accessible location as there is no universal master key.
Troubleshooting
The key is difficult to turn in the lock cylinder
Apply a small amount of graphite powder or silicone-based lubricant to the key and insert it into the cylinder to work the mechanism.
The U-shaped bar will not slide through the unit
Ensure the lock is fully unlocked with the key and that no debris is blocking the interior channels of the hitch lock base.
Pros and Cons
Pros
- Highly visible yellow color acts as a strong visual deterrent
- Constructed from resilient cast steel to prevent forced entry
- Universal fit accommodates most 50mm couplers
- Adjustable to 11 different locking positions for a secure fit
- Corrosion-resistant coating protects against environmental wear
Cons

Setup, Compatibility & Care
Installation is straightforward and requires no tools. Simply place the base of the lock onto the trailer coupler, insert the U-shaped steel bar through the unit, and use one of the two provided keys to lock it into place. Ensure the bar is clicked into the most secure position for your specific coupler size to eliminate unnecessary movement. For care, wipe the lock down occasionally with a damp cloth to remove grit or road grime that could collect near the keyway. During the off-season, applying a light spray of silicone-based lubricant inside the lock cylinder can help prevent internal seizing or stiff operation.
