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

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

This lock is easy to use and seems to be theft proof!!

Best security for an RV.

Best lock on the market and American made

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

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

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?

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

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!

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.
