With Engel Transverse Duct Flange (TDF) Rollformers, you can roll form your own seal-able flanges on transverse duct joints during the fabrication process for both fittings and straight duct applications. Engel TDF T25b Rollformers feature patented TDF Rolls that produce flange on the machine’s left-hand auxiliary and have unique snap-in corners. Optional rolls are also available for the clip. These are the only transverse duct flange machines on the market certified to comply with SMACNA Duct Construction Standard (DCS) T-25b based on actual laboratory tests across the full range of water gauges. The original Engel TDF T25b Rollformer has a capacity of 18-26 gauge mild steel and operates at a speed of 75 ft/min. Our newest model has a capacity of 16-24 gauge mild steel at a speed of 50-60 ft/min.
