Advantages of the TruTool F 300 Seam Locker

TruTool F 300 closes Pittsburgh seams in straight or bent ducts in an independent roll-glide process. The sheet thickness range extends from 0.75 mm to 1.25 mm construction steel. The seam closer works conveniently and quietly; the infeed ensures continuous and tight seams. There is no need for conversion for processing of shaped and curved pieces.
