CZC AUTO Trailer Tongue Coupler Lock Adjustable Trailer Coupler Pin Lock, Dia 1/4 Inch, 3 Inch Effectice Length Fits 1 Inch to 3 Inch Latch-Type Coupler for Towing Boat Truck RV Car Trailer

Works pretty well. I haven’t had it long enough to give it a great review but it is just like another one I’ve had for a few years and I believe it’s going to hold up just as well I believe this is a good product

I bought other ones but the shaft was not long enough. This one works perfectly on R pop up camper.

This did exactly what I needed it to do.

Best one I have ever had

The shaft is very cheap and can be easily bent/ broken with your bare hands. After a week of being installed WITH THE RUBBER CAP COVERING THE LOCK, the key could not be inserted. A little bit of oil and it is working as it should yet again. Many reviews state that the lock cylinder can be easily slid off. THE LOCKING PORTION IS DIRECTIONAL. If you put it on backwards, the lock will slide right off with minimal effort, if installed correctly, it will not slide off. Not a great lock, really more for appearance to keep the thieves away but provides very minimal security.

It locks but if you pulled on it the lock didn't hold and the bolt would slip through the lock. I tried multiple ways to secure it but it wouldn't hold a lock. I had to run to O'Reilly's where I was able to buy an actual, functioning one and Amazon was kind enough to allow a return.

Doesn’t work at all. Wont even stay on when locked, can pull right off. I gave them a chance because I needed something in a hurry - but they don’t work in the slightest, believe the reviews and don’t buy these.

Sorry to report...but this is a cheaply made lock. I've used several similar locks from the major lock brands and there products usually last about 5 years or so before needing to be replaced.This one is poorly constructed. It is very difficult to get the key in the lock. When you look at it, you can tell it is not made to last.When I received it and opened the package, I was like crap, I just bought something that should be sold in a dollar store.After fighting to get the key into the lock every time, I threw it away after four months.

We used this on our boat trailer tongue. The next weekend i picked up the boat, the lock fell off before i even put the key in and would no longer stay locked. Garbage, do not waste your money!

Long pin for all sizes.

Secure, works smoothly, not much else to say.

Extremely cheap. Poor quality. Broke on first use.
