High quality, great price, fits variety of trailer ball szes
Master brand is known for high quality, which usually comes with higher price than competitors. Lots of research done to find a very solid lock for new camper trailer. This lock was reasonably priced, in line with other 'foreign'-named options. Lock arrived quickly AND much better theft protection than a lock through the trailer latching mechanism.

Great Lock for Trailer Security!
I bought the Master Lock Universal Trailer Coupler Lock, and it's been a great addition to my RV setup. It fits perfectly on my 2-inch coupler. It’s solid, durable, and provides that extra layer of security when I’m parked at campgrounds or when my trailer’s stored. The lock is easy to use—just slide it on, lock it in place, and I feel much more confident leaving the trailer behind. It’s made of heavy-duty materials, so I’m not worried about it rusting or breaking. Overall, this Master Lock is a great value for the price and provides peace of mind that my trailer is secure. I highly recommend it to anyone with a trailer or RV!

Great solid lock
This lock has some weight to it. It works great and feels solid. It didn’t fit on my utility trailer but that’s due to my trailer and not this lock. I gave this one to a friend and it has worked on his trailer flawlessly. Definitely worth the money. If it had actually worked on my trailer tongue I’d definitely be keeping it.

Très bien. Va peut-être décourager les voleur de bas de game. Mais va retarder les experts. Acheter pour le prix et à la demande des assurances. J'ai aussi acheté une serrure pour la poignée de la main. Bon prix pour en décourager quelque un. Reste à voir si il va rouillé et être difficile à ouvrir. Abitibi Québec Canada
