I like having the one key for both the ball coupler and hitch pin.
Have been using this on my fifth wheel with Anderson hitch. It is the only one I could find that would work.
I like this unit
I have used this on 3 different trailers. It works with each size coupler. It will at least slow down someone who is intent on stealing a trailer. After one year I have not had any issues with the locks or the keys.
The Tri-ball trailer coupler works great, just a reminder you do need to wipe the ball couplers off after removal to prevent grease from going in your storage box
Will not work on a DEMCO hitch. The cable that comes out of the tumbler mechanism wont allow the lock to work. It seemed like a great idea but it seems like it is made for less expensive hitches.
Serves its purpose to deter a thief with limited, or no tools from stealing our trailer but not sure how it would hold up against bolt cutters. But just having some security is helpful. Would recommend to anyone considering it.

Still works as good as new, giving peace Of mind that a potential thief could not easily hitch up the trailer and steal it. The steel pin does show some minimal rust but it has not impacted the functionality of the trailer coupler.
This will work for me.
It works great and has protected our scout trailer for over a year in spite of rising crime in the area. The only problem is that we needed extra keys which could not be obtained locally. That adds to the locks security.
I procured a new piece of towable farm equipment this black friday shopping week and needed an affordable locking system. I was looking for a tongue lock as well as a latch lock, so the Curt Tri-Ball trailer couple lock fit the bill. It arrived fast and is easy to use. I typically use the BOLT system of locks, but this piece of equipment just needed a more cost-effective solution. I am VERY pleased with this product and will likely buy it again if I keep finding good deals on needed towable equipment.
Great product! Ordered several of these, work fine! I like this design because they fit various size couplers, since we have more than one trailer. Very easy to install and hardly noticed from a distance. Great theft protection.
I bought on for my travel trailer, I liked it so much I purchase 2 more for my box and flatbed trailers. I like the different balls sizes and the cable lock.

I know that while trailer and hitch locks do provide additional security, they are not 100 percent theft proof. I had wondered if they had possibly cut the both the latch lock and cable to remove the Curt lock. I can only recommend looking at using a surround style lock like part # ML389DAT. Again it will not be theft proof however it would be difficult to cut off.
Sorry I haven't had the opportunity to use it yet I have it as universal backup.

Sorry I have not even used it. I just keep it for a standby.
Neat little device. It stows away in a nice little ball and the keyhole is protected by a sliding door to keep out dust and dirt. It probably won't stop a serious thief but it will deter a lazy opportunistic one. Good buy.
Very nice! Time will tell if it does the job!!
along with the wheel lock, my trailer is safe
This is perfect for my needs.
I have a utility trailer and a camper trailer. This product is certainly adequate to discourage most thieves.
Works great on multiple trailers.
Fit perfectly on my travel trailer.
it'll keep someone from stealing my tra iler
Just what I was Looking for. Fast Shipp ing
It is the product I am giving a 1 star. The Curt Tri-Ball Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Ball Couplers is poor excuse for a deterrent to criminals at best. The thin wire could easily be cut with a small wire cutter. I did not take it out of the packaging until a week ago when I needed to leave my trailer at the tire shop. Too much time has passed for me to return it now, so I am stuck with three worthless couplers I purchased about six months ago. Very disappointed etrailer would offer such a poor product.

I have pulled these items to see what you are saying, and you are correct it looks like this is just not made to fit well on the Demco coupler. It seems to me that the lock will still engage, just not very tight with this coupler. If you would like a coupler lock that will fit the Demco that you have, you could always use part # ML389DAT. This does not use the locking cable, but instead hugs the front of the coupler to keep it secure.
