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

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.

The seller was super responsive and the product fits like a glove. I upgraded the puck lock to a Mul-T-Lock that provides more security and is harder to drill. A bit more of an investment but it will probably slow someone that’s up to no good down. A lot. I plan on getting detachable chains to install as well but for now I keep them locked to the frame.

Heavy, but good quality lock.

Well built and very easy to use. I recommend removing your safety chains as well.

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

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.

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.

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

should have bought it direct from the company

Very well made and heavy-duty
