TD Duct Brake—Power

Bending Duct that has a TD Flanged Profile on each side cannot be done on an ordinary Hand Brake or Press Brake. TD Brakes utilize segmented spaced bars with a height equal or greater to that of the TD Flange height to remove the Flange from the bending action, and thus allowing for the 90 degree bend. Tennsmith HBT series (Hand Brake Transverse) do this manually; Vicon’s TDX Duct Brake does this mechanically. Though each does it differently, they are alike in that they succeed in removing the Flanged Profile from the equation by creating space in the bending area.
