I have some other cell phone cases, mounts, etc. and I am just wondering if their is any sort of industry standard size for these things? The reason I ask is because I have a PanaVise Model: 777 ClipCaddy Holder that claims to hold anything with a belt clip, but that led me to wonder if those round buttons are of a stanrard size or if the industry is all over the place on those.
