Security Door Controls Blog

Since 1972, SDC has manufactured popular electrified access control hardware like bolt locks, strikes, EMLocks® and egress devices in America while most of our larger competitors manufacture overseas. Designed, engineered and built in America means SDC products are readily available with standard one week lead times for most products.

With a robust toolbox of over 35,000 access and egress control components, SDC’s code compliant products form turnkey solutions for almost any door opening imagined.

With a visually appealing and functional design, SDC Door Prop Alarms are compatible with all access control systems, but can also function as a stand-alone solution. Now you can support positive access control and security behavior at any facility.
