RETRUE trailer hitch and coupler locks for towing security, including ball mount lock, hitch pin lock and trailer coupler locks.

Heavy-duty trailer coupler lock praised for solid construction and push-to-lock convenience. Customers said "very secure," "fits perfectly," and "works great in all weather conditions." Some noted protection cap issues flying off. One customer found the throat too narrow for their trailer. Overall, customers appreciate the robust build quality and fail-safe security.

This lock will last a long time.

This is a very solid lock, a little more then I expected, yet will work wonderful for my application on a very old gate.

Almost Excellent

Seems heavy duty. It came with a small section of the silver coating flaking off. Otherwise seems well made. We’ll see how it holds up.

Excellent fit for large coupler locks.

Very happy with this product. Fits well, goes on easily, robust build quality, even comes with a flexible cover that fits over the lock cylinder to prevent contaminants from entering the lock cylinder. I’m very happy with this purchase.

Not bad!

Seems to be of nice quality

Unfortunately, I could not use the lock as the throat was just a bit narrower than my trailer requires. Construction wise, it appears to be nicely built and is surprisingly heavy. If my trailer coupler was narrower, I would have kept this lock.

Good fit

Fits well and locks very securely. The rubber cap wouldn't fit well the way it laid on my trailer and flew off. Sprayed the lock with silicone to keep it waterproof.

Heavy duty lock that should easily hold up for the life of the trailer!

Quality lock

Nice lock, heavy construction. I use it in conjuction with a ball lock when stationary and when towing to keep my trailer secure.

Nice lock

This coupler lock fits perfectly on my race trailer and feels very solid once installed. The wider span makes it easy to get a proper fit, and it locks up tight with no play. It installs quickly and gives good peace of mind when the trailer is parked. Well made security accessory and definitely worth having.
