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 Deadbolt Retraction: From the outside, a physical key retracts the deadbolt, which unlocks the outside lever so it retracts the latchbolt for authorized users.
  
• Single-Motion Life-Safety Egress: When the deadbolt is projected, the inside lever retracts the latchbolt and deadbolt simultaneously, unlocking the outside trim. This ensures occupants can exit the room instantly with a single motion.
  

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 16 Million Cycles: Independently verified to withstand 16 times the cycle requirements for Grade 1 certification, ensuring this hardware will outlast the building it is installed in.
  
• Lever Sag Prevention: 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.
