I use my flightcase lid as a table-top for my laptop, keyboards, controllers etc. I riveted this into the side of the lid so I could loop cables and leads through it, much like looping a guitar lead through the strap so you don't pull it out accidentally. It's very sturdy and high quality. It has the added convenience of being sprung, so it stays 'closed' and out of the way.
I don't use it to carry the flightcase, but it'd do the job no problem. It's much sturdier-feeling than the handle I actually do use. The grip is quite comfortable, too.
