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

Excellent product and keeps us safe at storage and at campsites.

Very substantial lock. Any lock can be broken eventually, but this will be extremely difficult and likely anyone wanting to steal an RV would pass this one up, or make enough commotion to draw your attention.

Best lock on the market and American made

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

Fits my 2017 Airstream perfectly -- Yes its pricey but so was the trailer. I feel much better about leaving it unattended now that this solid metal lock has the ball secured. HIGHLY recommended!!! Easy on and easy off! Dont waste your time or money with the U shaped locks they dont fit Airstreams!

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.
