SDC LR100VDK-22 QuietDuo LR100 Series Von Duprin Field Install Retrofit Electric Latch Retraction Kit, 22, 36" 48" Opening

Upgrade your door hardware to deliver controlled, quiet egress and secure access with the Security Door Controls LR100VDK-22 QuietDuo LR100 retrofit kit. This field-install latch retraction kit converts Von Duprin 22 Series mechanical exit devices into electrically retracted, doggable devices—allowing the motor to retract the latch and hold the pushpad in the dogged position for momentary or sustained operation. Designed for 36"–48" openings and powered by DC, the LR100VDK-22 provides dependable, low-noise performance that complements surveillance and monitoring systems in hospitals, offices, and secure facilities. Because it installs to existing hardware, the kit reduces replacement costs and minimizes downtime while improving access control integration with electronic controllers and building management systems. The QuietDuo motor keeps operation discreet in noise-sensitive environments while maintaining the physical security and reliability you expect from Security Door Controls. Ideal for retrofit projects that demand fast installation, compatibility with Von Duprin 22 devices, and smooth integration with broader security and access control strategies. Order the LR100VDK-22 to modernize exits, improve traffic flow, and strengthen building security.
