This TDF hand folder is purpose-built for HVAC duct fabrication, offering both cam lock and gear lock designs to create any size TDF flange with precision. It supports sheet thicknesses from 1.2–1.5mm and working widths up to 2000mm, delivering clean, consistent folds for reliable duct connections.

   Ideal for small cross-section ductwork down to 200×200mm, it produces both TDF/TDC profiles and Pittsburgh lock seams with ease. With interchangeable A/B blades and a minimum folding angle of 40°, it adapts to diverse duct forming needs, making it an essential tool for efficient, professional duct production.
