Great lock from a great company!
I couldn’t be more impressed with this trailer lock. From the moment I took it out of the box, it was clear this is a serious piece of hardware. The heft and solid construction give me peace of mind. And the customer support I've received from Proven Industries has been amazing -- despite my best efforts I managed to purchase the wrong size, and the customer support team has been responsive and incredibly helpful!Bottom line: this lock is worth every penny.

Very sturdy lock that is seems easy to use. Came exactly as expected. Unfortunately I ordered the wrong size for my trailer, but the seller, Proven Industries, has been very responsive in helping me figure out exactly what I need and facilitating the exchange.

Great… but double check if you have cables vs. chains
I’m pretty happy with it. Super solid, easy install EXCEPT my trailer has cables instead of chains. (Karavan 5x8)The bottom plate doesn’t quite have enough room to get the larger cylinder on all the way, so I have to figure out something with the cables… so not an issue with the lock, but just beware of chain/cable placement and also the size of the hooks.
