Reese Towpower 72783 Trailer Coupler Lock, Adjustable with 6 locking positions and fits 1-7/8-inch, 2-inch, and 2-5/16-inch couplers.

Works great the bright color makes it easily visible to deter thieves. Simple to use attaches easily to trailer hitch and removes just as simple. I am sure the durability will not be a problem.

Reese has been around a long time, been a reputable business that makes good products. I have owned several variation of their hitches, balls, receivers. So I didn't hesitate on this. I'll admit that I with this lighter version mainly because I needed next day delivery and the other was not. But, this fit perfect, no issues, serves its purpose and is a good deterrent. Packaged great, 30 second install, great price, can't complain at all.

This is not a high level security trailer lock but I am very pleased with it for the price. It is solid construction and works easily. Heavier than expected. I would recommend for anything that needs basic protection.

I found it difficult to release the lock with the keys. Not sure whether I just had to wear the keys in a little or learn just how to do it. Seems like you have to push the key in firmly while turning it.

Great product. Recommend for any trailer.

Quality construction, easy use

Fits well, easy to use, very sturdy. Would buy again

I bought these to lock up our pop-up trailer that sits most of the year. It feels very strong and heavy duty, and would be difficult to cut off, hopefully. Prevents someone from putting it on their hitch. Recommend!
