The Corbin Russwin CLX33903-123D is a premier Grade 1 electrified cylindrical lever lockset designed for high-traffic commercial security and seamless access control integration. Featuring a Fail Safe (Power to Lock) function and the sophisticated Salvador curved lever design, this electromechanical lock ensures life safety compliance by unlocking the exterior trim during power loss while maintaining a free interior egress at all times. Built with EcoFlex™ technology, it boasts an incredibly low 10mA current draw at both 12VDC and 24VDC, making it an energy-efficient choice for modern smart buildings. This 3-hour fire-rated unit includes an 8-pin ElectroLynx® connector for simplified "plug-and-play" installation, an L4 keyway for secure key control, and a durable satin chrome finish, providing a robust, non-handed solution for demanding architectural hardware specifications.
Function: Fail Safe - Outside lever locked when power is applied and unlocked upon power loss. Inside lever remains free at all times. Key retracts latchbolt regardless of electrical state.
