The Corbin Russwin CLX33903-NZD Electrified Cylindrical Lever Lockset is the "set it and forget it" gold standard for modern commercial access control, blending Grade 1 durability with the sleek, architectural profile of the Newport (NZD) lever. Engineered with a Fail Safe function, this lock ensures the outside lever unlocks automatically during power loss for critical life-safety compliance, while the inside lever remains free for immediate egress at all times. What truly sets the CLX33903 apart is its integrated EcoFlex technology, which sips power at a mere 10mA–20mA, and the ElectroLynx 8-pin connector that makes wiring as simple as plugging in a phone jack. Complete with a versatile L4 keyway and a robust 10-year mechanical warranty, it’s the high-efficiency, high-security solution for high-traffic environments that refuse to compromise on style or reliability.
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.
