Since 1972 SDC products have been Designed, Engineered and Built in America while most of our larger competitors manufacture overseas. Our new condensed catalog provides streamlined access to a robust toolbox of over 35,000 access and egress control components that form turnkey solutions to address almost any door opening imagined.


SDC’s locking systems can be found in virtually any application where access control of a door is required. We’re particularly adept at new or retrofit applications of 1 – 10 doors, where 80% of the security door and hardware market exists.

We provide savings and profits to our partners through:
