I use these for rack mount amps. I was introduced to the captured nut rack, I like it. I have had so many rack screws strip out, if too many strip then you have to replace the whole rail, with these you just replace the captured nut assembly, if it strips. These probably wouldn't work to well if your gear constantly gets banged around, I'd probably upgrade to the heavier duty model. It's usually just me loading and unloading my gear, so I feel confident that these will work great. The rear hatch does seem a bit flimsy so we shall see. All in all seems to be a good case.
