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

This is the best lock housing for a hitch coupler out there at this time. This is for my 1985 Airstream Sovereign (Remod) and it is an absolute beast. It’s expensive. But a missing trailer is worse and more expensive. The heart ache alone is worth the money. Get a GOOD puck lock and do your research since there are many choices and all have their vulnerabilities. YouTube has many videos of locks failing so you can make a wise choice. This model of coupler lock will NOT store your safety chains. And this is a problem since some thefts have occurred by the thieves hooking up the chains only and driving off with the trailer. But this gets harder to do the larger the trailer. Look into adding an internal GPS tracker so should your trailer wander off on its own you can send the police to its exact location. This too in my opinion is worth it in peace of mind. In a nutshell, I am very happy with this lock and do not believe a better choice exists. Buy this. Now go get a really good puck lock. And a GPS tracker. And maybe a HD padlock for the safety chains. Or make the chains removable. Some have added a wheel lock. Thieves are expensive.... :(

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

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.

Only downside is that there were no instructions included so installation involved a few minutes of trial and error.

Someone will have to really work to steal my Airstream

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.

Not many locks out there for Airstreams. Heavy duty, bolt cutter proof! As a mechanical engineer I find the design Amazing!

Best lock on the market and American made

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

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.
