With the Erdi D341-60 seaming pliers, you can easily bend, fold, and seam thin sheet metals like zinc and copper right on site. The 45° angled jaw gives you smooth access to tight angles, recessed areas, and upright edges. Its 60 mm jaw width applies consistent pressure across the metal surface, creating crisp, uniform folds without buckling. Forged from quality steel with a lap joint and measuring 273 mm in total length, these pliers deliver the control and dependability you need for demanding roofing, flashing, and sheet metal projects.
