Sargent 28-11G38 LL Classroom Security Intruder Lever Lockset, Extra Heavy Duty

Function Information:

The Sargent 28-11G38 LL is an elite-tier Grade 1 Extra Heavy Duty Cylindrical Lockset specifically engineered for modern school safety protocols and high-security institutional environments. As a flagship model in the Sargent 11-Line Series, the "Intruder" function allows for immediate lockdown from the inside of a room, providing a critical layer of defense during emergency situations. The 28-prefix ensures this lock is supplied with a Sargent 6-pin LA Keyway cylinder, offering professional-grade security and seamless integration into existing facility master key systems.

Engineering Beyond the Grade 1 Standard

While most commercial locks strive to meet the minimum ANSI/BHMA A156.2 Grade 1 requirements, the Sargent 11-Line completely redefines the category. Independent laboratory testing has confirmed that this hardware is in a class of its own:

• 12 Times the Industry Standard: Tested to exceed 10,000,000 (Ten Million) cycles. This is 12 times the 800,000-cycle requirement for Grade 1 certification, ensuring decades of maintenance-free service in high-traffic corridors.
• Extreme Torque Resistance: The 11G38 is built to withstand over 3,000 in/lbs of torque on the lever. This is 3 times the force required for Grade 1 status, providing unmatched protection against "broomstick" attacks and extreme vandalism.
  
• Zero Lever Sag: Utilizing high-carbon steel spring cartridges, the LL lever remains perfectly horizontal for the life of the product, eliminating the unsightly "droop" found in lesser latchsets.
• 10-Year Limited Warranty: Sargent provides a decade of protection with no service required to maintain the warranty, offering the lowest total cost of ownership in the industry.
  

Critical Intruder Security Function (ANSI F110)

The 38 Classroom Security Intruder Function is a vital component of modern lockdown protocols, allowing staff to secure a room instantly without stepping into a dangerous corridor.

• Double Cylinder Control: The 11G38 features cylinders on both the interior and exterior. A physical key in either cylinder locks or unlocks the outside lever.
• Safe Interior Lockdown: During an emergency, a teacher can use their key from the inside of the room to lock the exterior lever. This ensures the room is secure without the teacher having to open the door or expose themselves to threats in the hallway.
• Fail-Safe Interior Egress: For absolute life safety, the inside lever is always free. Regardless of the locking status, occupants can exit the room instantly at any time, ensuring 100% compliance with NFPA 101 Life Safety and ADA accessibility codes.
  
• Visual Security: Because the outside lever becomes rigid when locked, it provides immediate physical confirmation that the door is secured.
