Flexible Conduit?

I came across this photo in my travels:



Is that yellow stuff some sort of flexible conduit for data or av wiring?

Yes .

As shown in the pic it is for the LV wiring. The open trim rings confirm this.

There is a product called ENT that can be used for line voltage. One brand here is blue, while the LV version is orange.
