I've got a bunch of the little black TSA-approved combination locks, and they appear to be practically useless, at least for hard (e.g., Pelican) checked cases. Roughly half the time they are completely gone when I retrieve the bag at the other end. On one trip last year, I had two on my Pelican 1610 -- one was gone and the other had been wrenched open (probably just with a pair of pliers) and was just hanging there in a curled mess. ![]()
I assume that the reason these locks are so wimpy is so that -- if for some reason the TSA key (which I assume most baggage-handling thieves have anyway) doesn't work, they can easily cut the lock off. But it logically follows that anyone ELSE can cut them off just as easily... <_<
I've resorted to just using heavy zip-ties, and really pulling them TIGHT, which makes them virtually impossible to twist off with pliers, and somewhat difficult (more difficult than a TSA lock anyway) to cut off. But I sure wish there was a really heavy-duty TSA lock that I could use on one side of a case (and zip-tie the other). I just can't find one!
