Professional Classroom Security (ANSI F84)

The 05 Classroom Function (often categorized with the G37 logic in the 6-Line series) provides administrative personnel with total control over corridor access while prioritizing life safety.

• Keyed Exterior Control: The outside knob is locked or unlocked exclusively by a physical key. This ensures that unauthorized individuals cannot change the locking status of the door from the corridor.
  
• Fail-Safe Interior Egress: The inside knob is always free for immediate exit. Occupants can never be locked inside the room, ensuring 100% compliance with NFPA 101 Life Safety codes.
  
• Deadlocking Protection: Features a deadlocking latchbolt that prevents "shimming" or unauthorized manipulation with tools when the door is closed.
  
• Classic OB Design: The OB Ball Knob offers a timeless architectural profile with a comfortable, ergonomic grip that has been a standard in institutional hardware for decades.

Built for Institutional Durability

The Sargent 6-Line is recognized as a "standard duty" lock that performs with institutional strength, offering a cost-effective alternative to Grade 1 hardware without sacrificing security.

• Exceeds Grade 2 Standards: Certified to ANSI/BHMA A156.2 Series 4000 Grade 2, this series is tested for hundreds of thousands of cycles to ensure long-term service in schools and offices.
  
• Corrosion-Resistant Chassis: The internal mechanism is constructed of high-strength steel with zinc dichromate plating, protecting the lock from internal rust and environmental wear.
  
• Fire-Rated Integrity: With the 24-prefix, this lockset is UL/cUL Listed for use on 3-hour fire-rated doors, making it a code-compliant choice for commercial hallways.
  
• Sargent LA Keyway: Supplied with the industry-standard 6-pin LA Keyway cylinder, allowing for seamless integration into existing facility master key systems.
