Function Information:  

The Sargent 24-29-6G37 OB is a professional-grade Grade 2 Cylindrical Classroom Knob Lockset engineered for reliability in medium-traffic educational and commercial environments. As a cornerstone of the Sargent 6-Line Series, this lockset is designed for doors where key-controlled security is paramount. The 24-prefix indicates this unit is UL Listed for 3-hour fire doors, while the 29-prefix specifies the inclusion of a 2-3/4" backset and #808 ANSI Strike, making it the industry standard for commercial hollow metal frames.

Professional Classroom Security (ANSI F84)

The 37 Classroom Function (ANSI F84) provides administrative personnel with total control over corridor access while prioritizing life safety. This function is specifically designed to allow the door to be locked or unlocked from the outside without affecting the ability to exit from the inside.

• 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 side.
  
• Fail-Safe Interior Egress: The inside knob is always free for immediate exit. Students and staff can never be locked inside the room, ensuring 100% compliance with NFPA 101 Life Safety and local building codes.
  
• Deadlocking Protection: Features a deadlocking latchbolt that prevents "shimming" or unauthorized manipulation with tools or credit cards 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 or fire safety compliance.

• 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, offices, and retail spaces.
  
• 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 and stairwells.
  
• Sargent LA Keyway: Supplied with the industry-standard 6-pin LA Keyway cylinder, allowing for seamless integration into existing facility master key systems.
