Sargent 8204 WTL Storeroom Function Mortise Lockset - LA Keyway
The Sargent 8204 WTL is a heavy-duty Grade 1 Mortise Lockset specifically designed for high-security storage areas, mechanical rooms, and any sensitive space requiring permanent restricted access. As part of the legendary Sargent 8200 Series, it is widely considered the industry benchmark for structural integrity and cycle life, far surpassing ANSI/BHMA A156.13 Series 1000 standards. The 8204 Storeroom or Closet Function (ANSI F07) ensures that the exterior is always secure, requiring a key for every entry while maintaining absolute safety for anyone inside.
Essential Storeroom Security (ANSI F07)
The 8204 function provides a high-intent security protocol where the door cannot be left unlocked by mistake. It is the primary choice for "back-of-house" security in schools, hospitals, and commercial offices.
- Always-Locked Exterior: The outside lever is rigid at all times. Entry can only be gained by using a physical key to retract the latchbolt.
- Automatic Re-Locking: Once the key is removed, the door is instantly secure. There is no toggle or button that could accidentally leave the room vulnerable.
- Fail-Safe Interior Egress: For critical life safety, the inside lever is always free. Occupants can exit the room instantly at any time, meeting all NFPA 101 and ADA accessibility requirements.
- Auxiliary Deadlatch: Features a stainless steel deadlocking latch that prevents "shimming" or unauthorized manipulation of the latchbolt when the door is closed.
Professional WTL Escutcheon Trim
The WTL trim configuration (WT Escutcheon with L Lever) offers a clean, linear architectural aesthetic paired with industrial-strength protection for the door and the lock body.
- WT Escutcheon Plate: This heavy-duty, wrought-metal escutcheon provides a robust mounting surface that reinforces the door face and protects the LA Keyway cylinder from tampering, physical abuse, or vandalism.
- L Lever Design: The L Lever features a modern, sleek profile that is fully ADA compliant. It allows for effortless operation with only 30° of rotation required to retract the latchbolt.
- Unmatched Durability: The Sargent 8200 Series is independently verified to exceed 14 million cycles—14 times the requirement for Grade 1 certification—ensuring the lowest total cost of ownership in the industry.
- Anti-Sag Engineering: High-carbon steel spring cartridges and cold-forged steel hubs ensure the L Lever remains perfectly horizontal, preventing "lever sag" even in the most high-frequency environments.
