Always used a fish tape, now I'm on the glow rod crew
I spent 8 years pulling cable through commercial drop ceilings with a steel fish tape. Last month I had a job in an old office building in Columbus where the conduit took three 90 degree bends before the box. I fought that tape for 45 minutes and got nowhere. My apprentice handed me a 1/4 inch fiberglass glow rod set and I ran it through in one shot. The stiffness and the glow tips made it way easier to see where it was going in the dark plenum. Now I use the rods for any run over 30 feet with tight bends. Anyone else made the switch and gone back to steel for certain jobs?
Did you try the rods on a really long straight run yet? That's the one spot where I still grab the steel tape, because the rods can bow and bind in a straight pipe once you push past 40 feet or so. Keep both on the truck and match the tool to the run, that's the trick.
