About Us

Crown Fire Door Products is a new company with exciting, brand-new products! And it all began with an observation and an idea…

Chuck Noble, FDAI, of Certified Fire Door Company, is a fire door expert. Working in the commercial door industry for over 15 years, then certified by the NFPA as a Certified Fire Inspector I, he began inspecting fire door assemblies when the NFPA-80, 2007 Edition required all fire doors be inspected and tested annually. With every inspection it became more clear: clearance requirements were the most common issue for fire door assembly non-compliance.

With no easy solution for compliance in sight, the only remedy was to shim the frames or replace the door and/or the frame altogether. But Chuck had an idea. And so, the research and development began, UL testing followed, and Crown Fire Door Products, Inc., emerged with the 90-minute answer to excessive clearances.

We are proud of our products and their UL ratings; a testament to how well our products work! On this site you’ll find more information on products, ratings, codes, testing, and things to watch out for when purchasing fire door accessories. Check it out!
