Sargent 24-6G04 OB Storeroom Knob Lockset — US26D Satin Chrome

The Sargent 24-6G04 OB is a commercial-grade cylindrical storeroom function knob lockset finished in US26D Satin Chrome (626). Engineered for high-traffic institutional and commercial environments, this lockset delivers the dependable, key-controlled security that facility managers, contractors, and architects rely on for storerooms, supply closets, server rooms, and restricted-access areas.

Storeroom Function — What It Means for Your Application

The storeroom function (also referred to as a storage function lockset) keeps the outside knob always locked — entry is granted only by key at all times. The inside knob is always free-turning for immediate egress. There is no push-button or turnpiece to accidentally leave the door unlocked. This makes the 6G04 function ideal for:

• Storerooms, supply rooms, and inventory areas
• Server rooms and IT closets
• Maintenance and custodial access doors
• Any restricted-access opening requiring consistent key control

Specification & Compatibility Notes

The Sargent 6 Line cylindrical lockset platform is compatible with standard commercial door preparations and integrates with Sargent's V-10 restricted and standard keyway systems — supporting master keying, grand master keying, and keyed-alike configurations. When specifying for a project with an existing Sargent key system, confirm the keyway and cylinder option with your hardware schedule. For projects requiring lever hardware to meet ADA accessibility guidelines, comparable storeroom-function lever locksets are available in the Sargent 10 Line and 7 Line series.

The Sargent 24-6G04 OB is an industrial-grade Grade 2 Cylindrical Storeroom Knob Lockset designed for high-security commercial applications where doors must remain permanently locked to unauthorized entry. As part of the dependable Sargent 6-Line Series, this lockset is engineered for longevity in medium-traffic environments like schools, hospitals, and office complexes. The 24-prefix confirms this unit is UL Listed for fire doors with 2-3/4" backset and #808 ANSI Strike, the standard configuration for commercial hollow metal door preparations.

High-Security Storeroom Function (ANSI F86)

The 04 Storeroom Function is the premier choice for mechanical rooms, janitorial closets, and IT suites that require restricted access at all times. This function is designed to eliminate human error by ensuring the door is never accidentally left unlocked.

• Permanent Exterior Lock: The outside knob is always rigid and cannot be turned. Access is granted exclusively by using a physical key to retract the latchbolt.
  
• Automatic Re-locking: The door is instantly secure the moment the key is removed. There are no buttons or toggles on either side that could leave the room vulnerable.
• 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 auxiliary latchbolt that prevents "shimming" or unauthorized manipulation with tools when the door is closed.
  

Engineering and Institutional Performance

The Sargent 6-Line is built to outperform the baseline requirements for Grade 2 hardware, providing facility managers with a cost-effective alternative to Grade 1 locks 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.
  
• 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 Safety: With the 24-prefix, this lockset is UL/cUL Listed for use on 3-hour fire-rated doors, maintaining the integrity of fire barriers in commercial corridors.
