Are there any code issues with running CAT6 and Coax thru flexible duct that is not part of a ventilation system?
Basically I want to use something like this as conduit into an unfinished attic instead of PVC: http://www.homedepot.com/p/Speedi-Products-3-in-x-96-in-Round-Aluminum-Flex-Pipe-EX-AF-396/202907340
The attic is dusty and full of insulation. So I want something flexible that can curve back up to keep the dust and insulation from falling into the living space/closet
