History of Proven Locks

HOW WE BEGAN

Our story began with a family trailer being stolen with over $40,000 dollars' worth of
equipment in it. The real unfortunate part was how we chose to secure our trailer
with a low grade coupler lock which ended up costing us thousands.

In efforts to make sure this would not happen again we set on a path to develop the
best coupler lock in the industry today. In order to do this we knew we would have to
start from the ground up.
This is why we have chosen to manufacture all of our products out of the strongest
materials available and to manufacture our products in the United States. Rest assured
we are fully committed to providing you with the best security products on the market
today!
