With the rechargeable battery-operated TruTool F 301, you can lock Pittsburgh seams on straight or curved ducts in the sheet thickness range 0.45 mm – 1 mm for mild steel. There is no need for refitting when processing formed or folded pieces. The adjustment to the sheet thickness is automatic and the forward feed guarantees a consistent and tight seam. For example, with the 4 Ah rechargeable battery you can therefore cut up to 76 meters in mild steel and a sheet thickness of 1 mm.

  • Flange height and sheet thickness – Suitable for flange heights of 9 mm – 13 mm and for sheet thicknesses of 0.75 – 1.25 mm.
  • Excellent process reliability – Automatic adjustment to the sheet thickness. This therefore always gives you consistent seam results.
  • Area of application – With the TruTool F 300, you can close seams on straight and curved ducts.
  • The perfect combination – The rechargeable battery achieves a runtime that is up to 60% longer due to the Power-Head-Technology and brushless motor.
