Yes, I found that Gibson site also. But I could not find anyone actually selling those. I have no doubt they can be made. Just wondering if they exist in the real world, as in through distribution of some kind, with a min qty less than 1000. I have non-metallic conduit, but now with rust stains from the straps. I know they make PVC straps. Maybe those are the only two kinds normally used, PVC and steel.
