Park Tool is the gold standard for a reason, don't buy knockoffs expecting the same quality.

Velcro strips are solid but idk, do they ever lose their stick after a while with the heat from cables? I tried something similar once and after a few months the adhesive just gave up and everything flopped down. Maybe it was just the brand I grabbed though.

and then there's the whole thing about the fire suppression system too. My cousin runs a hot dog cart in Portland and he thought he could get away with just a regular kitchen fire extinguisher under the counter. Turns out the health department up there wants a specific type of hood system with a fusible link that drops if things get too hot. He spent three weeks fighting with the city over that one little piece of metal. Did your buddy have to deal with any of that fire code stuff on top of the grease trap mess?

I dunno, my cheap mount's been fine for three years now.

Lineco flexible PVA saved my old atlas, worked perfectly without cracking.
