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

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

Best lock on the market and American made

Someone will have to really work to steal my Airstream

Very well made and heavy-duty

Bought this lock for my Airstream and love it!!!

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

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

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!

Fit my hitch like a glove.

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