Sargent 28-65G04 KL Storeroom Function Cylindrical Lockset
Function Information:
The Sargent 28-65G04 KL is a professional Grade 2 Cylindrical Lockset engineered for high-security storage areas, mechanical rooms, and any opening that must remain permanently locked to unauthorized traffic. As a cornerstone of the Sargent 6500 Series, this lockset offers a "standard duty" footprint with performance that exceeds the rigorous demands of ANSI/BHMA certification. The 28-prefix specifies the inclusion of the 4-7/8" #808 ANSI Strike, the standard for commercial hollow metal frames, while the KL design features the sleek, ergonomic L-lever paired with the decorative K-rose.
High-Security Storeroom Function (ANSI F86)
The 04 Storeroom Function is specifically designed for secure areas that require restricted access 24/7. It eliminates the risk of a door being accidentally left unlocked.
- Permanent Exterior Lock: The outside lever is always rigid. Access is only possible by using a physical key to retract the latchbolt.
- Automatic Re-locking: The door is instantly secure as soon as the key is removed. There are no buttons, toggles, or thumbturns that could inadvertently leave the room vulnerable.
- Safe Interior Egress: The inside lever is always free for immediate exit. Occupants can never be locked inside the room, ensuring 100% compliance with NFPA 101 Life Safety and ADA accessibility codes.
- Deadlocking Latch: Features a 1/2" throw stainless steel latch with a deadlocking auxiliary bolt to prevent "shimming" or credit card attacks.
Built for Institutional Durability
While categorized as a Grade 2 lock, the Sargent 6500 Series is built to outperform industry standard cycle requirements, providing a cost-effective alternative to Grade 1 hardware in medium-traffic zones.
- Enhanced Cycle Performance: Engineered to exceed the 400,000-cycle ANSI/BHMA Grade 2 requirement, ensuring a long life cycle in commercial offices and public buildings.
- Hurricane & Windstorm Rated: Certified to comply with strict Florida Building Codes (FL# 2998) and TAS standards, proving its structural integrity under extreme pressure.
- Vandal-Resistant Chassis: Constructed with a cold-rolled steel housing and zinc dichromate plating to protect internal mechanisms from environmental wear and corrosion.
- ADA Compliant KL Lever: The linear L-lever design is ergonomically shaped for ease of use, meeting all Americans with Disabilities Act standards.
