Advantages of the TruTool F 305 Seam Locker

In a cold forming process the power fastener cuts and forms the connecting element out of the working material. In this process, the upper sheet is tightly and positively connected to the lower sheet. With the power fastener you can join coated or uncoated workpieces. There is no limit to the variety of materials. There is no need for pre- or post-processing. And there are no costs for fasteners like screws or rivets. You can work quickly, since two joins per second are created.

Superior efficiency point for point

  • Rapid stroke rate – up to two joining points per second
  • High tool life with corresponndingly high efficiency
  • Powerful 1400 watt motor
  • Machine available as electric- and cordless-version


  • Ventilation works and climate control technology
  • Container construction
  • Electrical and chemical appliances
