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

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

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.

Best lock on the market and American made

Easy to use and looks good.

Does intended job. Heavy unit. Unlocking can be a pain. It fits loosely but totally secure. I feel more secure when I leave my rig unattended.

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.

Reviewed many locks and we are happy that we chose this one. It would be difficult for a thief to compromise the steel casing.

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

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.

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