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

Very well made and heavy-duty

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

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.

Best security for an RV.

Heavy, but good quality lock.

Fits as advertised but the puck is loose at the bottom someone could use a pry bar and brake the puck pretty easy.

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!

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

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.

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.
