With its powerful 1200 watt motor and high operating speed, this seam locker is an even stronger version of the TruTool F 300. It closes Pittsburgh seams in straight and curved conduits with an independent roll/glide process. The sheet thickness ranges from 0.03 to 0.05 in. mild steel and the integrated infeed ensures continuous and tight seaming. There is no need for conversion for processing of shaped and curved pieces. Adaptation to sheet thickness is automatic. On-site assembly is also possible.
