This universal 3-ball trailer coupler lock offers security whether your trailer is hitched up to your vehicle or left unattended. Latch lock secures the coupler when your trailer is hooked up and when the lock ball is inserted during storage.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.
Shortly after buying this item one of the balls broke off.The lock itself was easily opened without the key.

Well that is not good at all! This item does have a limited lifetime warranty. Let me get you over to our customer service department for them to see what we can do to further assist you.
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.
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.
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.
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.
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.
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.
So easy to use and I feel so much better knowing my camper cant be hauled away without my permission!
This is perfect for my needs.
I have a utility trailer and a camper trailer. This product is certainly adequate to discourage most thieves.
so far has worked ok when used.. I would guess the local meth heads have not figured how to defeat it without destroying the coupler
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.
trailer got stolen this lock on it

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.
Great product.
These two items resolved my issues
Just as described rugged looking deterr ent.
Fits perfectly. Extra key is awesome
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 like these locks. They work to slow a lazy thief down.
Excellent Value. Probably as secure as others, but more versatile. Planning on buying more.
Just what I was Looking for. Fast Shipp ing
along with the wheel lock, my trailer is safe
Fit perfectly on my travel trailer.
Works great on multiple trailers.

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.
