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.

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.... :(

Built by Brinks, if someone steals your trailer with this 50lb hunk of steal latched on it let them have it because they are one bad mother and you dont want to mess with them. Its so overkill its like wearing full body armor to a water gun fight.

Best lock on the market and American made

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.

You never know if security is overkill until something is stolen. When I bought my Airstream, I wanted the best lock available. Theres a couple good choices, but this was the winner! If you have an Airstream, make sure you buy the specific AS lock, the others wont fit due to the cutout on the top. My nitpicks, 1. Its expensive! Ill say. 2. In order to open you have to insert the key into the bottom of the lock. Unless you lay on the ground, its hit or miss. Ill get a small mirror. You can insert a separate lock for the chains, but why? Some determined thief can still hook up to your safety chains with a tow truck and take off.

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

should have bought it direct from the company

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!

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