Instead of add-on flange, roll forming your own sealable flanges on transverse duct joints during the fabrication process has never been easier. The TDC flange, per SMACNA Duct Construction Standard (DCS T25a) specifications, is formed on the machine’s left-hand auxiliary, has unique, snap-in corners that eliminate spot welding. Optional rolls are also available for Z-Bar and TDC Clip.
