Wuko 1401 Sheet Metal Double Seaming Pliers PRO

The WUKO 1401 Double Seaming Pliers PRO are professional handheld sheet metal pliers designed for precisely closing double-lock seams, including flat double-lock seams. Engineered for metal roofing contractors and architectural sheet metal professionals, these heavy-duty pliers combine a high-leverage handle mechanism, angled parallel jaws, and smooth operation for controlled seam formation with reduced hand effort.

The WUKO 1401 features jaws inclined at 10°, allowing a greater bending angle to make further seam closure easier. Its lever mechanism delivers approximately 10 times the pressing force, while the spring-return handle automatically reopens the jaws for smoother, faster repositioning. A low-friction PTFE composite bushing helps maintain efficient movement, and the jaw opening can be adjusted between two positions to accommodate different seaming requirements.

Built for professional jobsite use, the WUKO 1401 features precision CNC-machined, oxynitrocarburized components for improved resistance to wear and corrosion. PVC-coated handles provide a comfortable grip, while a one-handed locking latch keeps the pliers securely closed during storage and transportation.

Features & Benefits

• Professional Double-Lock Seaming: Designed for closing double-lock seams, including flat double-lock sheet metal seams.
• 10° Angled Jaws: Inclined jaw geometry allows a greater bending angle, making further seam closure easier and more controlled.
