Review: Looks like a good quality product and works well. - I bought this for a trailer in France i have and it fits well onto the trailer towing hitch securely. Great visual deterrent. Happy that it would slow down anyone trying to steal the trailer. The product seems to be of good quality and locks together well.
Review: Great little hitch lock - Bought this for a bit of extra tow away security for a horse box and it fit the bill perfectly. Easy to use, does exactly what you would expect. Nice bright colours available (I chose yellow) to make it obvious that the lock is in place. Would certainly recommend if you just want some simple tow away security without it costing a small fortune.

## Questions & Answers

**Q: Any possibility I can order two items both with the same key set (two locks with four identical keys)? Thanks.**
A: Dear, each trailer hitch lock is equipped with two keys, and the key of each lock is different. The probability that you use one lock key to open the other lock is extremely small. Our trailer lock cylinder is made of copper crescent cylinder, which  quality is bettter and mutual opening rate is extremely low. Please trust to purchase!

**Q: how do I ge extra keys?**
A: CAUTION. A special key like this may not be reproduced at a locksmith.  The company may not provide one either or do so at a great expense.  
I have a Reese trailer tongue lock and no one had the blanks.  The company wanted $10 + shipping to send a copy.
Be aware of that before buying a lock like this.  The Master Lock locks have key with widely available blanks.

**Q: What is the inside dimensions of the u-bolt?  My coupler is 4" wide, so I need it to be at least 4".**
A: 3-7/8” inside the “U”.  You can probably take a 1/16” off each side of flange at bottom of the trailer hitch with a grinder to make it work.

**Q: Will this fit the various types of trailers?**
A: I think so, it will fit almost any of that sort of 50mm ball hitch because it is very easily adjustable

Good quality lock easy to fit. I think the plastic of the key fob is a bit flimsy but overall good value for the money
