MASC - Special Seaming Prism: Seam without damaging the material – work with precision down to the last detail

Specialist tool for clean seaming work

With the MASC - Special Seaming Prism, you can shape seams with control – without damaging the surface. This tool is the smart solution when you want to seam visible components while protecting the material and need maximum precision. Every detail matters, especially when working with coated sheets or delicate non-ferrous metals such as zinc, copper, or aluminum – and this is where the seaming prism really shines.

Whether for facade cladding, dormers, parapets, connections, or reworking edges: you’ll work cleanly, efficiently, and with modern tools – a real upgrade to your roofing tools and sheet metal tools.

How to use the seaming prism in roofing

The seaming prism is used as an auxiliary and guide tool to start, adjust, and precisely shape seams. Position it directly at the edge or in the seam area, guide the contour, and then use a hammer/soft-face hammer to finish the seam - without direct metal contact with the surface. Especially when bending transitions, working on interior/exterior edges, and handling tight details, it ensures even lines and a clean appearance.

Ideal in combination with a bending tool

In the workshop or on the job site, it perfectly complements your bending tool: After pre-bending with the bending tool, use the prism for precise adjustment, closing seams, and creating clean finished edges - especially for visible facade and roof finishes.
