A Day to Celebrate!

In 1972, SDC founder Art Geringer created the blueprint for the modern era of electrified access control door hardware and controllers. We proudly continue his commitment to innovation, skill and quality today.

Arthur V. Geringer, was born in 1923 and grew up in his father’s architectural hardware business in Chicago. After serving in the US Army during World War II he returned to civilian life in 1945. He settled in California and was employed at a major Los Angeles contract hardware firm before moving to an automatic door firm. While there, Art received his certification as an Architectural Hardware Consultant in 1952, allowing him to combine his industry experience with his energy and passion for innovation over the next 60 years.
