The nice thing about promoting industry standards is clever products to meet those standards will magically show up in big box stores and supply houses :-) Builders and electricians get used to doing it.

Apparently I spend more time roaming the aisles of the big box home improvement supply stores than you do (I am not proud of that, I just do(*)). I have seen it, and all the associated connectors. and alternatives, for years, although for various reasons I prefer to use the local electrical supply stores when possible to source items (yes, they can be more expensive for some items, but they can also supply items that only the pro's know even exist, so I prefer supporting stores that have that deep competency and supply sourcing). (*) I do not visit the local big box home improvement stores more than once a month or so, but whenever I do I also walk down the aisles which include electrical items even if I have zero reason to purchase any items just to level-set me list of items they stock.

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=1_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
sigs wanted for a response to the fcc's NOI for faster broadband speeds
Over here: https://docs.google.com/document/d/19ADByjakzQXCj9Re_pUvrb5Qe5OK-QmhlYRLMBY4vH4/edit Us bufferbloat folk have been putting together a response to the FCC's NOI (notice of inquiry) asking for feedback as to increasing the broadband speeds beyond 100/20 Mbit. "Calls for further bandwidth increases are analogous to calling for cars to have top speeds of 100, 200, or 500 miles per hour. Without calling also for better airbags, bumpers, brakes, or steering wheels, (or roads designed to minimize travel delay), these initiatives will fail (and are failing) to meet the needs of present and future users of the internet." Comments (and cites) welcomed also! The text is still somewhat in flux... -- :( My old R campus is up for sale: https://tinyurl.com/yurtlab Dave Täht CSO, LibreQos

Interesting… ENT is apparently plastic and has interesting snap fittings. Until this email, I’ve never even looked into it. Used plenty of the “ENT” boxes, but always just called them PVC (since that’s what the ENT stuff is apparently made of). EMT is way more common out here than ENT, and even where plastic is used, most seem to use straight electrical PVC (grey stuff usually) instead of of the ENT brand stuff. It really comes down to if the path is straight or complicated. If it's just poking straight through a wall to something adjacent on the inside or nearby, rigid pipe works fine, is easy enough to work with, and is readily available. However if the external "demarc area" and inside "media aggregation area" aren't nearby or are separated by a convoluted path once running inside walls and ceilings is taken into account, flexible conduit is obviously easier, and ENT is a readily available option most electricians are going to be familiar with for that. It's literally where the term "smurf tube" came from AFAIK. It's not itself a brand-specific thing (indeed multiple manufacturers make it) and is just yet another type of raceway defined by NEC, but the blue Carlon stuff is well known. -- Brandon Martin

They're great for just pushing through a wall penetration to something directly adjacent on the inside, though. At that point you might as well for for 2", honestly. -- Brandon Martin
