This panel is made of pretty much thick metal - it's enough, so it won't flex, or move.
Bought it for a bit different purpose than mounting in a rack - I've made a "patch panel" for a pedalboard from it. Paired it with neutrik lockable connectors. This also helped to get rid of some cable clutter across pedalboard, connecting your in and out, fx loop send and return, and sometimes trigger signals to act as a footswitch for the amp. Put a PowerCON connector there too, so setting up would take less time.
