Universal Coupler Lock Universal Coupler Trailer Hitch Security Lock Adjustable Storage Security Heavy-Duty Steel fits 1-⅞", 2", and 2-5/16" couplers Replaces#72783

Shipping was fast got it before the scheduled delivery date, good job Auto Parts Depot. Coupler lock fits great for a 2 5/16 ball but will fit other size hitch balls. Locks very easy and unlocks easy. Definitely secures the trailer or RV. I would recommend buying this for securing your trailer or RV.

Haven’t installed it yet, but it’s the same product I’ve used before. I bought this because the vehicle I owned was stolen and the keys for this lock were in my vehicle! I now have to cut the old lock off my trailer to install the new one. I like the updated key design and have full confidence that my trailer will be safe. Now if I could catch the SOB’s that stole my car I’d be all set!

Received this lock today and it fits great as described. Easy to lock and unlock etc... My main concern is it does not feel like the strongest item in the world. I think with a pry bar and a few seconds you could easily break it. I would recommend a secondary security system in place if you have a trailer that's accessible easily.

This lock and the locking system isn't good at all. Locked it once and the next time to try to unlock it the key functions went to the dogs. Don't waste your money. I guess you get what you pay for.

I like this lock however it does not fit our travel trailer with a 2 5/16" ball straight up and down as shown in pictures. the tongue is a bit wider then the shank so i have to cock it over to one side and the shank will lock on the end notch. It does fit my 2" boat trailer which has a more modern unique tongue. I would take the chance and buy it again.

I bought this for a Wells Cargo trailer which is a 2 5/16 ball. It does not fit the trailer rolled lip on the tongue. It is too narrow.I have another smaller trailer that will fit this coupler.

I got this product just in time. I keep it on my trailer and I am pleased with how easy it is to use. It would certainly slow down any potential theft. I use this in conjunction with a lock pin I bought separately.

If you purchase this lock, have a secondary security system. The thief was able to break this lock apparently very easily and take off with the trailer quickly. We had a security camera that took at picture of the thieves as they stole the trailer.
