Proven IndustriesModel 2516-AS Trailer Lock, Fits (1997-2019) 2 5/16-Inch Airstream Couplers, Made in The USA (Black)

Game changer tool/ accessory. If you really want to secure what's important, this is the one! Our airstream at least has a fighting chance at not getting hauled away by someone who's not us. It is easy to use, very cool looking (and therefore seems pretty boss-like at first glance), hefty and the 'look' of it shows it means business. Hard to find a lock that isnt easy to break. This one is the best we've found. $$ but the peace of mind is so worth it.

Love this lock, works great and gives me peace of mind. Great product very recommend.

I have purchase this for my travel trailer. It is very durable, functional, it is not too heavy and great value in my opinion when it comes to protecting your investment.

Holy moly! I went through 3 different hitch locks before I found this one that ACTUALLY FITS! works on a 1978 Airstream.

This lock system is heavy duty, fit my Airstream perfectly. So I purchased one for my enclosed trailer as well 😄

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.... :(

Great product

Fit our 2016 Airstream International like a glove. Looks solid & well made. Didn’t see instructions in box but was easy to figure out. It was pricey but a lot cheaper than having your trailer and possessions stolen!
