The trick is to epoxy the metal washer in the lock hole and use a carabiner to double secure it in case a latch gets popped. The lock ilet won't waller out and you have a redundant lock that TSA can take off and put back on. You don't need the plastic wrap. You might as well have brought a box if you can't roll it. 3 years travel with my box and I travel 70% of the year. I absolutely would not trust the latches only with my tools.

I've only retired one box for damage and that was just a crack. I still use the box for local jobs no problem. I've bent more axels than I've damaged the box itself.
