steel roll up doors

This cut works great for steel slated rollup doors.  Notice the cut is towards the center if it was to close to the wall there would be no room to pull the slats.  If the door was all the way down and you had to cut the bottom bar do a pie cut to fit the saw head in there and cut the bottom bar.  These doors are usually riveted every other slat.  So if you pull with no movement pull the one above or below.  If the doors are riveted every slat cut on the sides thus defeating the rivet you don't have to make the cut all the way down but you can if you would like.  Remember the part of the door not cut will go upward into the drum making a loud sound it is normal.
