Hager 3857E Intruder Classroom Mortise Lockset – Grade 1 Escutcheon Trim
The Hager 3857E Intruder Classroom Mortise Lockset is a premier security solution designed for modern educational facilities, municipal buildings, and high-risk commercial environments. This Intruder Classroom Function (ANSI F32) set is specifically engineered for emergency situations: it allows a teacher or administrator to lock the outside lever immediately from the inside using a key. This "double cylinder" design ensures that staff can secure a room without ever stepping into the hallway, providing a critical layer of protection during a lockdown.
As a BHMA Certified Grade 1 device, the 3857E is built to withstand the most demanding physical environments. The Escutcheon (E) trim design offers a sleek, continuous vertical plate that provides a clean, professional appearance and superior protection against tampering. The heavy-duty mortise lock body is constructed from case-hardened steel, ensuring smooth mechanical performance for millions of cycles.
Rapid Lockdown & Industrial Strength
The Hager 3857E combines high-level security with ADA compliant lever handles. A vital safety feature of this lockset is that the inside lever is always active, ensuring immediate egress at all times, regardless of the locked status of the exterior. For a permanent and stable mount, the escutcheon plates are secured using thru bolts, providing a high-strength, through-the-door connection that keeps the hardware perfectly aligned even under heavy daily use.
