MASC - Angle Seam Opening Set – controlled opening of closed angle seams

When an angle seam is closed, you need a tool that opens it precisely – without destroying it. The MASC - Angle Seam Opening Set is your specialized system for gently and evenly opening closed angle seams on roofs and facades. It lets you replace damaged panels precisely without bending adjacent components or unnecessarily scratching the surface. Exactly how modern sheet metal and roofing work should be done: in a controlled, clean, time-saving manner.

Who is this set made for?

For you, if you need professional roofing supplies or sheet metal worker supplies for daily use – and want to properly handle repairs to standing seam or angle seam systems instead of forcing them open “any old way”. Complementing the tin snips you use on site, this tool set gives you controlled access to closed seam areas.
