The metal handle that I put on my pedalboard has been stepped on several times, and has been perfectly fine. Because it's mounted directly to the pedalboard, and has rubber feet underneath the board (which the screws go through), any weight applied to it is directly transferred to the stage without the board even flexing. It's about as idiot-proof as I can make it
even they keep making more powerful idiots... The key is really that it saves me from pretty much any normal "oops I didn't mean to step there" accident. If Wiley Coyote decides to drop an anvil onto my pedalboard, I'm probably out of luck.
