Is there any sort of nook/cranny that's out of the direct walking path? Is it possible to perhaps takeover the 4 corners, and clearly mark the area where gear can go? aka "Inside glow tape line."? People don't walk to the edges at corners anyways, so that's a possibility. Are your catwalks made out of pipe? Mine have the same diameter pipe everywhere, so I could hang excess instruments or whatnot on an unused side. Excess accessories, though, becomes harder. I like the shelf idea. I'm not sure if you need the shock cord though. If you made this shelving unit floor to top-rail height, with just a could U bolts, to immobilize it, It would probably do quite well. (Assuming this is on the catwalk itself.) As long as nothing is hanging out of the shelves, you shouldn't have a trip hazard or whatnot. Perhaps some sort of sliding doors, or something, could ensure that people don't leave something sticking out. What was your concern about dropping stuff though? Behind the shelves? Where?
