Proven Industries Model 2517-AS Trailer Lock, Fits (2020-2023) 2 5/16-Inch Airstream Couplers, Made in The USA (Blue)

Heavy, but good quality lock.

Fit my hitch like a glove.

Sold! Love this thing. Fits our Airstream like a dream. I did think that it would be able to hold the chains as well but that would have to be a VERY big device. I can walk away from our Airstream with a lot more confidence that it will still be there when I get back.

This thing, I hope, is fool proof. Wish the key was on the side instead of down. I have had it for a couple of weeks and my RV has not been stolen yet.

I dont worry any longer. The little yellow Reese thing had me looking out the window all the time. Now I never check. Peace of mind is Great. The chains go inside very easily. I do wish it would secure my electrical connector. If they cant plug in. The brake wont release on the trailor. For just a little add on it would give you even more security.

Excellent product that is well designed, easy to use and works great.
