Lockformer Transverse Duct Connector (TDC) T25a Rollformers
With Lockformer Transverse Duct Connector (TDC) 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.
Introduced in 1982, the original Lockformer TDC Rollformer continues to be the only transverse duct connector machine on the market that produces rollformed flanges certified to have passed all the functional criteria tests from 1/2” W.G. to 10” W.G. to comply with SMACNA Duct Construction Standard (DCS) T-25a*. Today the Lockformer TDC T25A Rollformer is available in the original standard configuration with a capacity of 18-26ga steel at a speed 60 ft/min and our latest model which has a capacity of 16-24ga steel at a speed of 70 ft/min with optional inboard and outboard roll sets.
