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

This lock is easy to use and seems to be theft proof!!

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.

I dont worry any longer. The little yellow Reese thing had me looking out the window all the time. Now I never check. Peace of mind is Great. The chains go inside very easily. I do wish it would secure my electrical connector. If they cant plug in. The brake wont release on the trailor. For just a little add on it would give you even more security.

Very well made and heavy-duty

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!

Secures entire hitch ball assembly. Pricey, but so is the cost of a stolen Airstream. Hoped it would secure safety chain hooks but no, they’re too thick.

Someone will have to really work to steal my Airstream

Heavy, but good quality lock.

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

Very substantial lock. Any lock can be broken eventually, but this will be extremely difficult and likely anyone wanting to steal an RV would pass this one up, or make enough commotion to draw your attention.
