The seam bundle for clean edges and controlled seams

With the MASC seam bundle, you get two perfectly coordinated helpers for modern sheet metalworking: the 2-Phase Soft-Face Hammer plus the MASC - Special Seam Prism. The result: precise seams, clean lines, and a surface that retains a visibly high-quality finish even on coated sheets. Whether on parapets, verges, dormers, or in facade cladding - you work faster, more precisely, and without unnecessary rework. Ideal if you want to bring your roofer tools and sheet metalworker tools up to a professional level.

Detailed use - explained specifically for the trade

Set, reposition and close seams - without surface damage

Position the Spezial seam prism directly on the edge or in the seam area. It serves as a guiding and pressure surface, allowing you to shape the seam in a controlled manner. You then finish the work with the 2-phase soft-face hammer: first position it with measured force, then compact it cleanly – without direct metal contact with the visible surface. Especially for inside/outside edges, tight connections and visible components, the prism ensures even seam lines and a professional look.

The perfect complement to the folding tool

After pre-bending with the folding tool, you finish the work with the prism and soft-face hammer: close seams, shape end edges cleanly and press transitions precisely into place. This is exactly where the bundle shows its strength – when dimensional accuracy, appearance and speed matter.
