The Lock that works!
This is my second proven lock I learned first hand how good they work at keeping your trailer safe. Someone tried to steal my 24foot car hauler they failed when they realized they couldn’t get the lock off. I just purchased a new car hauler as soon as I got home before I did anything else I ordered another proven lock. I highly recommend proven locks!

Seems stout, but still expensive. . .
Just got it in the mail and installed it on our trailer. It seems stout and hopefully deters thieves. I understand quality comes with a prices, but this price was a hard pill to swallow. I do appreciate the 10% military discount too, but to see Proven offer a 15% discount on Facebook the day after I ordered, and not allow me to grab that opportunity, was disappointing to say the least. Hopefully this lock stands the test of time and that bitterness goes away. . .

This was my 2nd order from Proven Industries and I’m just amazed at how much better I’m sleeping at night since I have put this on it has already PROVEN ITSELF TO BE WORTH every penny you charged for it.
