SDC LR100SGK QuietDuo Sargent Field Install Retrofit Electric Latch Retraction Kit, 8000, 36-48" Opening

Upgrade mechanical panic and fire-rated exit devices to modern access control without replacing the hardware. The Security Door Controls LR100SGK QuietDuo field retrofit latch retraction kit provides reliable electric latch retraction and sustained dogging so facilities can enable remote access, scheduled unlocking, or temporary push/pull operation while preserving code-compliant egress.

Built for installers and security integrators, this DC-powered retrofit supports 36–48 in door openings and 8000-series exit devices, making on-site upgrades fast and cost-effective. The QuietDuo motorized mechanism retracts the latch and depresses the pushpad quietly for a smoother user experience — ideal for hospitals, schools, and high-traffic commercial entrances where noise and uptime matter.

Designed to integrate with access control panels, building automation, and monitoring systems, the LR100SGK simplifies security deployments and reduces service calls. US-made and field-installable, it keeps existing hardware in service while adding electronic control and electric dogging capability.
