Interesting… I’ve always thought of that super-thin flimsy corrugated plastic cut side tubing (similar to this): https://www.mouser.com/ProductDetail/Panduit/CLT50F-C3?qs=gyp5g9lXdE5smA3BAFqGhA%3D%3D&mgh=1&gad_source=1 which (originally) came in a very bright blue and later black, orange, and many other colors. However, apparently ENT was a predecessor to that, I just hadn’t encountered it until now. I don’t recall even seeing it in the aisles at local HDs. I’ll have to look for it. For the most part out here, if it’s going behind sheetrock, contractors/electricians just run Romex or whatever in bare stud holes without any form of conduit. Owen
