I live in a one-story ranch with an unfinished basement and attic, in the middle of a project where I’ll have access to a bare, un-drywalled wall. I know that eventually I’ll want to run low voltage/Ethernet cable from the basement out to my attached garage, probably through the attic as the garage is only separated from the rest of the attic by Sheetrock.

I just don’t know how much Ethernet cable I’ll be wanting to run.

I think conduit would probably be the best for traversal/future proofing this, but I have no clue what kind to get.

Any suggestions? Things I should look out for?

    When our house was being built, we had them install a pipe chase from the basement near the fuse box to the attic, specifically for me to be able to run whatever cable I wanted to later on. This was done with 3" PVC (I think, I haven’t looked for a while).

    I’m seeing other people suggesting much narrower conduit, and I would have to advise against that. Let’s say you already have a couple of ethernet cables run through your pipe chase, and you want to run another one. Having plenty more room for the fish tape with the new cable attached is going to make it much easier to pull that new cable through.

    I would run the largest conduit you can fit.
