Sargent 8239 LE1L Classroom Security Function Mortise Lockset w/ Deadbolt - LA Keyway
The Sargent 8239 LE1L is the ultimate high-security Grade 1 Mortise Lockset, combining advanced "Intruder" classroom security with the massive physical strength of an integrated deadbolt. Specifically engineered for K-12 schools, universities, and government facilities, the 8239 Classroom Security Intruder Deadbolt Function (ANSI F33) allows staff to lock down a room instantly from the inside using a key. Part of the legendary Sargent 8200 Series, this lockset far exceeds ANSI/BHMA A156.13 standards, making it the premier choice for openings that require maximum resistance to forced entry and absolute life-safety compliance.
Dual-Cylinder Intruder Deadbolt Security (ANSI F33)
The 8239 function provides a multi-layered defense strategy. It allows for the projection of a heavy-duty deadbolt while simultaneously controlling the locking status of the exterior lever from either side of the door.
- Key-Driven Lockdown: A key from either the inside or outside retracts or projects the deadbolt. Projecting the deadbolt automatically locks the outside lever, preventing unauthorized entry.
- Deadbolt Protection: Features a 1" throw hardened stainless steel deadbolt for maximum resistance against kick-ins and physical attacks.
- Automatic Interior Unlocking: Regardless of the deadbolt's position, the inside lever retracts both the latchbolt and the deadbolt simultaneously with a single motion.
- Life-Safety Egress: This "single-motion egress" ensures that occupants can always exit the room instantly, fulfilling strict fire code and ADA requirements.
Heavy-Duty LE1L Escutcheon Trim
The LE1L trim configuration offers a clean, linear architectural aesthetic paired with industrial-strength protection for the door and the lock body.
- 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 provides a sleek, modern profile that is fully ADA compliant, allowing for effortless operation without requiring a tight grip, pinch, or wrist twist.
- Extreme Mechanical Life: 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 over decades of use.
- Anti-Sag Engineering: High-carbon steel spring cartridges and heavy-duty wrought steel hubs ensure the L Lever remains perfectly horizontal, preventing "lever sag" even in high-abuse environments.
