Sargent 8204 LNL Storeroom Function Mortise Lockset - LA Keyway
The Sargent 8204 LNL is a premier Grade 1 Mortise Lockset engineered for high-security commercial, institutional, and industrial applications. As a cornerstone of the Sargent 8200 Series, this lockset is designed to provide maximum resistance against physical abuse while offering the legendary reliability of a heavy-duty mortise chassis. The 8204 Storeroom Function (ANSI F07) is the industry standard for securing mechanical rooms, IT closets, and perimeter doors where unauthorized entry is strictly prohibited, but immediate exit is required.
High-Security Storeroom Function (ANSI F07)
The 8204 function is purpose-built for total access control. The outside lever is always rigid and locked, ensuring the door cannot be left accidentally unsecured.
- Keyed Entry Only: Entrance from the exterior is granted only via a physical key using the industry-standard LA Keyway.
- Constant Free Egress: The interior lever always allows for unhindered exit, maintaining strict compliance with NFPA 101 Life Safety Codes.
- Anti-Vandal Design: Because the exterior lever does not retract the latch without a key, it is highly resistant to "lever riding" and forced entry attempts.
Architectural Excellence: The LNL Lever Design
The LNL lever features a clean, contemporary aesthetic that complements modern building designs without sacrificing strength.
- ADA Compliance: The ergonomic LNL linear lever is fully accessible, requiring minimal force to operate, making it suitable for all public and private commercial spaces.
- Superior Return Springs: Equipped with high-strength internal springs that prevent lever sag, keeping the hardware perfectly horizontal throughout the life of the opening.
- Heavy-Duty Trim: The rose and lever assembly are constructed from solid materials to withstand high-frequency use in schools, hospitals, and government buildings.
