MASC - Standing-Angle Seam Opening Set - Controlled Opening of Closed Standing-Angle Seams

When a standing-angle seam is closed, you need a tool that opens it precisely - not destroys it. The MASC - standing-angle seam opening set is your specialized system for gently and evenly opening closed standing-angle seams in roofing and facade applications. This allows you to replace damaged panels precisely without bending adjacent components or unnecessarily scratching the surface. Exactly the way modern sheet metal work and roofing work needs to be done today: controlled, clean, and time-saving.

Who is this set made for?
