Sargent 28-11G24 LL Entrance Office Lever Lockset, Extra Heavy Duty

Function Information:

The Sargent 28-11G24 LL is an elite Grade 1 Extra Heavy Duty Cylindrical Lockset engineered for high-security environments where the frequency of use and potential for abuse are extreme. As part of the legendary Sargent 11-Line Series, this lockset is designed to provide maximum protection for building perimeters, office suites, and public entrances. The 28-prefix indicates that this unit is supplied with a Sargent 6-pin LA Keyway cylinder, ensuring professional-grade pick resistance and seamless integration into existing master key systems.

Performance Without Equal

While many commercial locks struggle to meet the baseline requirements for ANSI/BHMA A156.2 Grade 1, the Sargent 11-Line shatters industry expectations. Through independent laboratory testing, this lockset has proven to be in a class of its own:

• 10 Million Cycle Endurance: Tested to exceed the Grade 1 standard by 12 TIMES, enduring over 10,000,000 cycles. This unparalleled longevity ensures the lowest total cost of ownership by virtually eliminating replacement cycles.
  
• Extreme Torque Resistance: The 11G24 can withstand over 3,000 in/lbs of torque on a locked lever—3 times the Grade 1 requirement. This provides a formidable defense against vandalism and unauthorized entry attempts.
  
• Zero Lever Sag: Heavy-duty high-carbon steel spring cartridges ensure the LL lever design remains perfectly horizontal for the life of the building, preventing the unsightly "droop" found in inferior hardware.
• 10-Year Limited Warranty: Sargent stands behind this hardware with a decade of coverage that requires no service maintenance to remain valid.

Versatile Entrance & Office Function (ANSI F81)

The 24 Entrance / Office Function offers flexible security control, allowing staff to easily manage access according to the time of day or security needs.

• Push-Button Locking: Pressing the button on the interior lever locks the exterior lever. A physical key in the LA Keyway is then required for entry.
  
• Turn-Button Lockdown: Turning the interior button keeps the exterior lever locked until it is manually turned back. This is ideal for maintaining a secure "restricted" state for extended periods.
• Automatic Unlocking Logic: Rotating the inside lever or closing the door automatically releases the push-button (but not the turn-button), significantly reducing the risk of accidental lockouts.
• Fail-Safe Interior Egress: The inside lever is always free for immediate exit, ensuring 100% compliance with NFPA 101 Life Safety and ADA accessibility codes.
• Deadlocking Latchbolt: Features a 1/2" throw stainless steel latch with an auxiliary deadlatch to prevent "shimming" or credit card attacks.
