The smaller Gator-cases have a handle that stretches out a little when you grab it, but these larger ones (3U and over?), have a fixed bar for handle and so close to the rack body, that you can only get your fingertips under it.
If you're only irregularly lifting the case horizontally from flat on the table to another, it's fine. But load it with heavy gear and try carrying it by only one handle: NOPE! Terrible design flaw!
