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?
