here are a few pictures to show in essence what I do. The lock is just a cheapy that I use on cabinets at work. use the hockey puck master locks when camping. As you can see the big loop can go around a pole that holds the power box, I loop it around and lock it to itself under the box which makes it unable to be slipped off. Hopes this helps.
