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

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.

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

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

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

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?

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.

Best lock on the market and American made

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

should have bought it direct from the company

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