Tired of changing out a blown out 1" hp line from junction box to boom? Extend the hard pipe from boom to almost the wall where boom attaches. Use pipe straps where needed, Ideally you want the swivel as close as possible to bearings. Get a 90 deg 1" swivel and run your flex line into the bottom of this. End result flex line doesn't move or scrape on wall. I made this mod over a year ago and still no leaks!
