Von Duprin Exit Devices

Von Duprin is an Allegion company that manufactures exit devices of various kinds as well as electrical products. Von Duprin is known for bringing the first panic bar type device to the market in the early 1900's allowing for doors to be locked from the outside while allowing immediate egress from the inside. Von Duprin exit devices are recognized for their high quality and innovative technologies.

According to Allegion: "an independent study of more than 100 commercial facilities across the U.S. documented that Von Duprin exit devices require significantly less maintenance over a 30-year period than any other brand."

Here we will look at some of the most popular Von Duprin exit devices and options that are available. (Read our previous blog post about some exit device basics you should know)
