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.
