Security Door Controls LR100 Corbin Russwin Electric Latch Retraction Kit

Convert a compatible Corbin Russwin exit-hardware application to electrically commanded latch retraction for controlled entry. Electric latch retraction permits an access-control system to command the latch mechanism open, allowing authorized users to enter without manually operating the exit device from the secure side. The exit device remains the door’s mechanical egress hardware while the retraction function provides the controlled-entry interface. Security Door Controls LR100CRK is an electric latch retraction kit configured for Corbin Russwin hardware applications. It belongs where a controlled opening requires a release action from an access-control credential reader, remote release control, or other compatible access-control command source. This configuration is intended for doors where the exit device and its latch must work with an electronically controlled entry sequence. The Corbin Russwin-specific application distinguishes this kit from latch-retraction configurations intended for other exit-hardware platforms. Select it when the door uses compatible Corbin Russwin hardware and the project calls for electric latch retraction rather than a separate electric locking device. Confirm the exit-device configuration, door preparation, power arrangement, and access-control interface requirements before installation. The kit addresses latch retraction; it does not replace the need to evaluate the complete opening, including the exit device, door, frame, credential system, and release controls.
