Yay!!!Thank you!!! Now I just hope its dummy proof. Lol.
If you are punching for a DCT make sure to measure and mark the carto before you punch. If you get too low the end cap will block the punched hole, and if you get it too high it won't draw and fill properly. It doesn't have to be exact, just close. It is easy if you have a carto that has already been punched then you can just use it as a template.
Your first carto or two will take a few minutes but after that you can do them pretty quick.
