3" Straight Hand Seamer with Integrated Folding Tool

New!
CTH3SFT
The Crescent Wiss 3" HVAC Hand Seamer with Integrated Folding Tool is designed for sheet metal professionals, HVAC technicians, and contractors who need to bend, flatten, form, and fold sheet metal efficiently on the job. The 3-inch seaming jaws provide precise control for forming ductwork, flattening seams, and making adjustments during installation, while the integrated folding tool adds versatility for common HVAC fabrication tasks. Easy-to-read depth markings help improve consistency, and the ergonomic grips provide comfort during repetitive work. By combining seaming and folding capabilities in a single tool, it helps reduce the number of tools needed for HVAC duct fabrication and sheet metal forming applications.
