## Questions & Answers

**Q: Will this fit a bulldog hitch?**
A: it fits all ball sizes, but has problems with 2 5/16 balls due to the flange around the reciever its just a tad wide to fit squarely under the reciever- so the one on my travel trailer sits at an angle,if the U bolt section would have been made a 1/4 of an inch wider- would have been perfect

**Q: can i request a certain key, would like multiple locks to have same key as locks i already have**
A: Dear Customer: 
We are sorry that our keys can only be used for one lock, our trailer locks are delivered by Amazon and cannot be modified.
