Sargent 8225 WTL Dormitory Function Mortise Lockset - LA Keyway
The Sargent 8225 WTL is an industrial-grade ANSI/BHMA Grade 1 Mortise Lockset specifically engineered for the high-frequency demands of university housing, military barracks, and multi-family residential facilities. As a part of the legendary Sargent 8200 Series, it is widely recognized as the industry’s most durable mortise lock, far exceeding ANSI/BHMA A156.13 standards for cycle life and physical security. The 8225 Dormitory or Exit Function (ANSI F13) provides a comprehensive locking solution that combines a heavy-duty deadbolt with automatic interior unlocking, ensuring absolute occupant safety and intuitive operation.
Advanced Dormitory & Exit Function (ANSI F13)
The 8225 function is designed to provide residents with a secure "home-base" environment while meeting the most stringent life-safety and fire codes for rapid egress.
- Deadbolt Privacy & Security: A 1" throw hardened stainless steel deadbolt is projected or retracted by a key from the exterior or a thumbturn from the interior.
- Intelligent Exterior Locking: When the deadbolt is projected, the exterior lever is automatically locked, preventing unauthorized entry.
- Keyed Latch & Bolt Retraction: From the outside, a physical key retracts both the latchbolt and the deadbolt simultaneously, providing a smooth entry for authorized users.
- Single-Motion Life-Safety Egress: Regardless of the deadbolt's position, the inside lever retracts both the latchbolt and the deadbolt simultaneously. This ensures occupants can exit the room instantly with a single motion, fulfilling NFPA 101 and ADA requirements.
Heavy-Duty WTL Escutcheon Trim
The WTL trim configuration (WT Escutcheon with L Lever) delivers a sophisticated linear architectural aesthetic backed by extreme mechanical reinforcement.
- WT Escutcheon Plate: This heavy-duty wrought metal escutcheon reinforces the door face and protects the Sargent LA Keyway cylinder and thumbturn from tampering or vandalism.
- L Lever Design: The L Lever features a clean, modern profile that is fully ADA compliant, requiring only 30° of rotation for latch retraction—ideal for users with limited mobility.
- Exceeds 14 Million Cycles: Independently verified to withstand 14 times the cycle requirements for Grade 1 certification, ensuring this hardware will outlast the building it is installed in.
- Anti-Sag Engineering: High-carbon steel spring cartridges and cold-forged steel hubs ensure the L Lever remains perfectly horizontal, maintaining a professional look even after decades of high-traffic use.
