Von Duprin Strikes – The strike is the one of the most important components of the exit hardware.  Each manufacturer uses something different, and the Underwriter Certification is dependent on that strike.  To qualify for the UL rating, you must use the manufactures recommended strike.  Von Duprin offers about 19 different strikes and we stock all of them.

History of Von Duprin

The Iroquois Theatre Fire that occurred on December 30, 1903 in Chicago, Illinois resulted in 596 lives lost.  Carl Prinzler, who was supposed to attend the show that night, was spared from the tragic incident when he missed the show due to business.  During that time, it was common for theater doors to be locked shut as to keep non-paying people out.  That also meant that patrons inside the theater would be locked inside the theater.

Five years later on January 14, 1908, the lives of 174 children were lost when the Lakeview School at North Collinwood in Cleveland Ohio burned down.  Distraught by the loss of so many lives in both catastrophes, Prinzler decided a solution must be found.  He sought out his architectural engineer friend, Henry H. Dupont.  Together they worked to develop a new door exit device that allowed people to exit the building from inside while simultaneously locking others out.  They collaborated with Vonnegut Hardware Company to bring their exit device to market in 1908.  With their combined efforts, they dubbed the name Von Duprin, a compilation of all three names.

After numerous experiments and with lots of energy, effort and hard work put in, Von Duprin had finally developed a universally accepted product. From there, Von Duprin began with a simple four-page circular listing and describing all their exit devices. They continued to put out bigger and bigger catalogs which included their increasingly growing line of exit devices and parts.
