Hager 3495 ARC Grade 1 Intruder Classroom Lever Lockset
Function Information:
The Hager 3495 ARC is a heavy-duty, high-security cylindrical lockset specifically engineered to meet the stringent safety requirements of modern K-12 schools, universities, and government facilities. As an Intruder Classroom Function (ANSI F110), this hardware allows for immediate lockdown of an opening from the interior using a key, ensuring that occupants can secure the room without stepping into a potentially dangerous hallway. Featuring the modern, swept-in Archer (ARC) lever design, this lockset provides a contemporary architectural look without compromising on Grade 1 durability.
Enhanced School Security and Life-Safety Compliance
The Hager 3495 is the industry standard for safe-room protocols. The dual-cylinder design enables authorized staff to lock or unlock the outside lever from either side of the door. A critical feature of the Intruder Function is the integrated locking indicator arrow stamped on the interior rose, providing immediate visual confirmation that the door is secured. To meet strict fire codes and NFPA 101 Life Safety standards, the interior lever is always active and provides free egress, ensuring occupants can exit the room at any time during an emergency.
Industrial Strength and Modern Ergonomics
Built for high-abuse environments, the Hager 3400 Series is certified to ANSI/BHMA Grade 1, meaning it has been tested to withstand over one million cycles. The Archer lever is fully ADA compliant, offering an ergonomic grip that is easy to operate for all users. The lock chassis is constructed with heavy-gauge steel and zinc dichromate plating for maximum corrosion resistance. To ensure long-term structural integrity and prevent lever sag, the unit is installed with a secure thru-bolt mounting system that creates a permanent bond between the lock and the door.
