ISC West attendees visited us to see why our proven Delayed Egress solutions have led the industry since 1995 with the most choices and customization available. Also, they learned why SDC has been the premier manufacturer of popular electrified access control hardware like bolt locks, strikes, EMLocks® and egress devices - all Designed, Engineered and Built in America since 1972, while most of our larger competitors manufacture overseas. Come and see for yourself before the show ends!
