Engel Transverse Duct Flange TDF vs Slip on Flange

Instead of add-on flange, roll forming your own sealable flanges on transverse duct joints during the fabrication process has never been easier. Formed flanges are considered standard and compliant by SMACNA. Engel Transverse Duct Flange (TDF) Roll Formers and Lockformer Transverse Duct Flange (TDF) roll formers are the only transverse duct connector machines on the market certified to comply with SMACNA Duct Construction Standard (DCS) T-25a and T-25b (respectively) based on actual laboratory tests across the full range of water gauges. Engel Transverse Duct Flange (TDF) Roll Formers produce flange on the machine's left-hand auxiliary, and have unique, snap-in corners that eliminate spot welding. With a capacity of 18ga to 26ga steel at speeds of up to 75 ft/min, Engel TDF Roll Formers also feature optional rolls for Z-Bar and Clip. This video demonstrates the difference between the Engel Transverse Duct Flange (TDF) and a Slip-On Flange.
