Sargent 8255 WTL Office Function Mortise Lockset - LA Keyway

The Sargent 8255 WTL is a heavy-duty Grade 1 Mortise Lockset designed to provide versatile security and architectural elegance for professional office environments, administrative buildings, and upscale commercial facilities. As a cornerstone of the Sargent 8200 Series, it is engineered to withstand extreme physical abuse, far exceeding ANSI/BHMA A156.13 standards. The 8255 Office or Entry Function (ANSI F04) allows users to easily toggle between "free passage" and "keyed entry," making it the premier choice for suites that require restricted access during business hours and absolute security after-hours.

Versatile Office & Entry Function (ANSI F04)

The 8255 function is the industry standard for high-traffic office doors. It uses a face-mounted toggle mechanism that gives the occupant complete control over the door’s accessibility.

• Dual Operation (Toggle): The outside lever is made operative (unlocked) or rigid (locked) by the stop works toggle located on the armored front of the lock body.
  
• Keyed Access: When the exterior lever is toggled to the locked position, entry can only be gained by a physical key using the standard Sargent LA Keyway.
  
• Constant Life-Safety Egress: Regardless of the locking state, the inside lever is always free. This ensures that occupants can exit the room instantly at any time, fully complying with NFPA 101 Life Safety and ADA accessibility codes.
  
• Auxiliary Deadlatch: Includes a stainless steel deadlatch 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) delivers a sophisticated linear architectural aesthetic backed by extreme mechanical reinforcement.

• 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. Its ergonomic shape allows for effortless operation with only 30° of lever rotation required to retract the latchbolt.
  
• 14 Million Cycles: Independently verified to exceed the Grade 1 standard by 14 times, the Sargent 8200 Series provides the lowest total cost of ownership by virtually eliminating the need for replacement.
  
• Anti-Sag Technology: High-carbon steel spring cartridges and cold-forged steel hubs ensure the L Lever remains perfectly horizontal, maintaining a professional look for the life of the building.
