Sargent 6G37 OB Classroom Knob Lockset — US26D Satin Chrome

The Sargent 6G37 OB is a commercial-grade cylindrical knob lockset configured for Classroom function, finished in US26D Satin Chrome. Designed for schools, universities, and institutional facilities, this lockset delivers reliable, code-compliant security on classroom and similar interior doors where controlled access is essential.

Classroom Function — What It Does

The Classroom function (F84) means the outside knob is locked or unlocked by key from the outside — the inside knob always remains free for immediate egress. This configuration allows an instructor or staff member to lock the room from the corridor without entering, supporting both everyday classroom control and emergency lockdown preparedness. The inside knob is never locked, meeting life-safety egress requirements.

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.
