For easy and quick closing of mechanical lock standing seam.  Will close seams that measure 1/2″ on the top leg width. These seams can vary in height, but commonly stand at 1″ or 1.5″.

The manual angle seam closer is used to close the profile SPM 30/80. Carefully continuing the work tool avoids pressure points at the transitions. The ergonomic arrangement of the handles makes the SYSTEM RAU® angle seam closer particularly user-friendly. This tool shows all its strengths with extremely angled facade fronts. Of course, the angle seam closer can also be used for longer vertical and horizontal panels.
