Proven 400XL locks
I purchased these for my 2014 Roadhouse small toy hauler ramp. I cut some small rubber spacers to tighten them up and prevent rattling. These are way nicer and more stout than typical padlocks.

So far so good
I have only started using the 400XL Proven locks a week ago. It is nice having all the locks keyed alike. Making access to the trailer more convenient. Shipment arrived promptly and well packaged. The color match is as if they were made custom for my trailer. I am happy with Proven locks so far and plan to order another three for a second trailer that I have. Although my daughter wanted the sticker. Unfortunately, one is not provided, "maybe they include those with the second order". I explained . . . that her 4x4 machine is secure behind the new Proven locks.

The lock works like I'd hoped it would. I did have too make some modifications on the hasps of the trailer lock to get it to work. One improvement I would suggest would be to allow rotation of the bolt to get a better fit. Other than that, it will be my go to from now on.
