Sargent 8245 LE1L Dwelling, Dormitory Entrance Function Mortise Lockset - LA Keyway
The Sargent 8245 LE1L is a world-class Grade 1 Mortise Lockset engineered specifically for the high-security demands of university dormitories, military barracks, and multi-family dwelling units. As part of the prestigious Sargent 8200 Series, it is recognized as the industry standard for mechanical endurance and forced-entry resistance. The 8245 Dwelling Entrance Function (ANSI F12) provides a sophisticated double-cylinder locking solution, integrating a heavy-duty deadbolt with keyed control from both sides of the door to ensure maximum occupant protection in high-density residential environments.
High-Security Dwelling & Dormitory Function (ANSI F12)
The 8245 function is purpose-built for facilities where access control and privacy must be balanced with extreme physical security. It features a specialized double-keyed deadbolt system for specialized entrance requirements.
- Double Cylinder Deadbolt: The 1" throw hardened stainless steel deadbolt is projected or retracted by a key from either the outside or the inside.
- Automatic Exterior Locking: When the deadbolt is projected, the exterior lever is automatically locked, preventing unauthorized entry even if the latch is bypassed.
- Life-Safety Single-Motion Egress: Regardless of the deadbolt's position, the inside lever retracts both the latchbolt and the deadbolt simultaneously. This ensures occupants can exit instantly in an emergency, fulfilling strict fire and safety codes.
- Anti-Friction Latch: The 3/4" throw stainless steel latchbolt ensures smooth, quiet operation and reduces wear on the strike plate over time.
Heavy-Duty LE1L Escutcheon Trim
The LE1L trim configuration combines a clean, modern linear aesthetic with industrial-strength protection for the door and internal lock chassis.
- LE1 Escutcheon Plate: This full-height linear escutcheon provides a robust mounting surface that reinforces the door and protects the LA Keyway cylinders and internal components from tampering or vandalism.
- L Lever Design: The L Lever features a sleek, professional profile that is fully ADA compliant, allowing for effortless operation without requiring a tight grip, pinch, or wrist twist.
- Unrivaled Cycle Life: 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.
- Lever Sag Prevention: High-carbon steel spring cartridges and heavy-duty wrought steel hubs ensure the L Lever remains perfectly horizontal, maintaining a professional look for decades.
