Advantages of the TruTool F 140 Seam Locker

TruTool F 140 can also be used for stainless steel and is very well-suited for processing large radii. TruTool F 140 works on a continuous roll forming principle, thus ensuring air-tight closure without hammering. This permits processing of straight and curved sheets up to 1.4 mm. The surface structure is not damaged. The seam closer functions with an automatic in feed, which means that you can proceed without the use of force. Pre-settings can be made for sheet thickness without the use of tools.
