TruTool F 125

For closing angle and standing seams

The TruTool F 125 closes angle and standing seams with a spring-loaded hammer. This gives you tightly closed seams with consistent quality, even if there are fluctuations in the sheet thickness. The maximum flange height that can be processed is 40 mm. The free-standing tool allows you to work extremely well even in tight corners and angles.

For angle and standing seams

You lock the seam with consistently high quality, even in corners and angles.

Can be adjusted without tools

The sheet and fold thickness are controlled manually and minor variations in sheet thickness are evened out.
