Hardcast introduced Dyn-A-Matic Corners, a patented product that offers universal compatibility with TDC or TDF flanges. Dyn-A-Matic Corners can also be used with Hardcast’s four-bolt flange as well as most competitive bolt-on flanges. Dyn-A-Matic Corners are designed to fit most automatic corner machines. They can also be used by contractors that do not own automatic corner machines because they can also be inserted by hand. Each Dyn-A-Matic Corner features two pre-punched holes that allow duct sections to be secured together with screws so carriage bolt fastening is easy and efficient. Hardcast says the Dyn-A-Matic Corners are ideal for high-pressure, commercial applications.
