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.

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!

Just what I was looking for.

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.
