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

This thing, I hope, is fool proof. Wish the key was on the side instead of down. I have had it for a couple of weeks and my RV has not been stolen yet.

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.

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

Heavy, but good quality lock.

Sturdy lock for my needs - my second from this company - made in USA.

Best security for an RV.

should have bought it direct from the company

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.

Best lock on the market and American made

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.
