The Dyn-A-Matic™ HVAC ductwork corners offer compatibility with most flanges. They can also be used with the company’s four-bolt flange as well as most competitive bolt-on flanges. They are designed to fit most automatic corner machines. According to the manufacturer, the corners are also perfect for contractors that do not own automatic corner machines because they can easily be inserted by hand. Each corner features two prepunched holes that allow duct sections to be secured together with screws, assisting in carriage bolt fastening. Offering superior strength that helps stabilize ductwork, Dyn-A-Matic corners are ideal for high-pressure, commercial applications, says the company.
