Our Founder: A Tribute to Art Geringer

Electronic Security and Door Hardware legend, Arthur V. Geringer passed on September 5th, 2016 at age 93. Art was a door hardware innovator and pioneered the design and practical application of electricity to door openings for security and fire & life safety. As the inventor of numerous electronic lock designs, Art is credited with ushering in the modern era of access control hardware with his development of the 90° throw electric lock. Now commonly used, this creation opened the potential of electric locking capabilities and began the great migration to electric locking systems.

Whether securing a server room, office suite, corridor, or restricted-use area, the 7200 series provides the performance and flexibility today’s security professionals demand.

Power Without Wires. Security Without Compromise.

How do you deliver reliable electrified locking when traditional wiring isn’t an option? Now you don’t have to choose between aesthetics and security.

By pairing a SDC electrified cylindrical lock (7200 series) with a SDC wireless power transfer devices (WPT), you get a clean, code-conscious solution that brings access control to doors where running wires is impractical—or impossible.

Wireless power bridges the gap, delivering consistent energy across the door gap—no core drilling, no exposed wiring, no compromise to design.

And when applied in failsecure configurations, this solution ensures that doors remain locked during a power loss, supporting perimeter security and controlled access requirements.
