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

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.

It is very expensive, but the design and quality of workmanship are outstanding.

should have bought it direct from the company

Easy to use and looks good.

Great piece to equipment to keep my $78K Airstream trailer from being stolen.

Well built and very easy to use. I recommend removing your safety chains as well.

This is by far the best RV lock on the market today. Recommend it highly to all RVers.

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.

Secures entire hitch ball assembly. Pricey, but so is the cost of a stolen Airstream. Hoped it would secure safety chain hooks but no, they’re too thick.

Best security for an RV.
