Inventor of the Panic Bar Exit Device Since 1908

Von Duprin invented the first panic bar exit device in 1908 when Carl Prinzler introduced the first self-releasing fire and panic exit device, and has since been world-famous for manufacturing exit devices with innovative designs and meticulous engineering. Now an Allegion brand, Von Duprin life safety products have provided unparalleled quality, performance, and flexibility for schools, hospitals, stadiums, and public buildings for over a century. An independent study of more than 100 commercial facilities documented that Von Duprin exit devices require significantly less maintenance over a 30-year period than any other brand.
