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

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.

Excellent product that is well designed, easy to use and works great.

Best security for an RV.

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.

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.

Very Happy

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.

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

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

Great fitting product, amazing customer support. The lock that comes with it was okay, maybe offer it without a lock or offer a choice of lock brands like mul t lock or paclock?
