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

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.

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

Fit my hitch like a glove.

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.... :(

Fits as advertised but the puck is loose at the bottom someone could use a pry bar and brake the puck pretty easy.

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

Great fitting product, amazing customer support. The lock that comes with it was okay, maybe offer it without a lock or offer a choice of lock brands like mul t lock or paclock?

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

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.

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