Company Profile

Von Duprin was found in 1908, when the company introduced its "panic release bar" as a response to the life loss due to a fire incident in Iroquois Theater in Chicago in 1903. Indianapolis hardware salesman Carl Prinzler who escaped the disaster, determined to find a solution for the problem of public buildings, teamed up with Henry DuPont, his neighbor and an architectural engineer, and invented a panic release bar. The first model was introduced in 1908, and was marketed by the Vonnegut Hardware Company as Von Duprin. Since then, Von Duprin has been manufacturing the widest range of trim operations and exit devices, including mortise lock and rim-type, fire-rated, surface and concealed vertical rod, and other electrical options. The security-related products offered include electric strikes, electromagnetic locks, keypad-type access control systems and card readers.
