Stortz FALZ seamer II. Listed on the Stortz sale page as a Buschmann AccuSeamer. Used to seam my standing seam roof on a new home and garage. It is powered by a drill. I used a Rigid 18V with low speed, and it performed great. You can adjust the trigger speed to move at the pace you like. You won't be able to keep up with it at high speed. It will do single or double folds. 1st pass for single. Rotate the head and complete a double fold, all with the same unit. Also including a 1st stage hand seamer to do the first 6 to 12 inches to get started and finish the end if against a wall or can't run off the end for some reason. Below is from the website.
The AccuSeamer is used for the seaming of single and/or double standing seam roof panels
For Seaming 1″ or 1.5″ high profiles (Warning: Do not use on 2″ high profiles)
