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

Works great. The videos on the web site show fitting the safety chains in the lock as well. I tried about every combination and watched the videos several times and still no luck, the hooks are just a little too think. Maybe if the assembly that hitched in had another 1/4 inch of clearance.

Fit my hitch like a glove.

Heavy duty formidable lock, easy to install. Safety chains will not fit inside the lock collar, though. Also purchased a Brahma wheel lock as additional security. Both locks are expensive, but with both it would take a lot of work, and considerable noise to defeat them.

Someone will have to really work to steal my Airstream

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

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.
