Specialized use in sheet metalworking and roofing

The STUBAI double seam closing tool is used specifically for initial folding, finishing folding, and shaping double standing seam profiles. It is particularly suitable for work on already installed sheets, when machines or larger equipment can no longer be used. The beveled and polished working surfaces fit cleanly against the sheet metal and reduce the risk of material damage.

Ideal for precise finishing work on installed components

Maximum accuracy is especially important at transitions, edge finishes, connection sheets, and detail points. This is where the double seam closing tool shows its strengths. The stepped prisms provide secure guidance for different seam stages and help you close the double standing seam cleanly and in a controlled manner.
