I'm using CDL signature spouts this year for the first time and have had issues putting them on the drops all the way and straight. I use semi rigid tubing for everything and you can't push them on by hand, at least not when it's 10 degrees out. I made this simple tool for each of my 2 handed tools and it works great. It's a 1/2" nut ground to the correct angle and welded onto a 3/8" bolt which clamps right into the tool. It took me maybe 15 minutes to make two of these and saves me a lot of time and grief. I just thought it might help someone having the same trouble.
