Please forgive me if this sounds like a stupid question. I have seen the statement "Enclosed Gooseneck w/TPO" several times and cannot figure out what the TPO stands for? I have looked far and wide on the internet and still haven't found my answer. I did, however, find an interesting write up on what a Torque Tube is and how that works. Can someone please tell me what TPO stands for or what it means?
