Howdy Wrenches, I was wondering how everybody is dealing with expanding conduits on roof tops? Do we have an accepted best practice on this?. What I am really looking for is a way to starp long conduit runs on commercial rooftops in direct sun that allow movement and expanision joints to do thier job. Mahalo in advance!
