FREUND - Large Seaming Block with Handle | More control when seaming
Do you want to work cleanly when bending and seaming, and really feel in control? That's exactly what the FREUND large seaming block with handle is made for. The ergonomic handle gives you significantly more grip, especially with long seams or when working with work gloves. At the same time, the special plastic reliably protects sensitive surfaces – perfect for visible areas on roofs and facade cladding.
More grip, more feel, less loss of power
When seaming, the final bit of pressure and guidance often determines a clean result. With the slightly angled working surfaces (approx. 5–7°), you can apply it precisely, guide it in a controlled manner, and reduce the risk of slipping. Because the seaming block is made of plastic, no rust residue is generated – ideal when working with coated sheets or high-quality non-ferrous metals.
Expert tip: How to use the seaming block correctly
Use the seaming block for clean application and closing of seams, for folding, and for finishing edges on already formed profiles. You guide the tool along the seam edge and work with even pressure to fold the sheet layer in a controlled manner – without scratching the surface. Especially in plumbing supplies, it is the smart alternative to seaming irons or double seaming irons, when visible surfaces and coatings need to be protected. It perfectly complements your roofer tools and plumber tools – whether on standing seams, connections, or for detailed work.
