Sargent 11G05 LL Heavy Duty Office Lever Lockset

The Sargent 11G05 LL is a heavy duty, commercial-grade cylindrical lever lockset engineered for demanding office and institutional environments. Built on Sargent's proven 10 Line platform, the 11G05 delivers reliable latch operation with office function — making it a trusted specification for commercial contractors, facility managers, and architects sourcing Grade 1 door hardware for high-traffic interior applications.

Office Function — What It Means for Your Application

The Office (or Entry) function on the 11G05 provides keyed control of the outside lever. When locked, the outside lever is rigid and the latch is retracted only by key. The inside lever always retracts the latch freely, ensuring occupant egress is never restricted. This function is ideal for private offices, administrative spaces, and any door requiring controlled entry with unrestricted exit.

Key Benefits

• Heavy Duty Construction — Built to withstand the rigors of commercial door applications; designed for high-cycle, high-traffic use
• Lever Handle Design — ADA-accessible lever operation compliant with accessibility requirements for commercial buildings
• Commercial Grade Lockset — Suitable for office buildings, schools, healthcare facilities, and institutional environments
• Sargent 10 Line Platform — A well-established cylindrical lock series with broad cylinder and trim compatibility; accepts Sargent V-10 (ASSA) cylinders for master keying and large key system integration
• LL Trim Style — Lever-on-lever configuration providing a consistent, professional appearance on both sides of the door

Typical Applications

• Private offices and executive suites
• Administrative and staff areas in schools and universities
• Healthcare and medical office corridors
• Government and municipal office buildings

The Sargent 11G05 LL represents the pinnacle of cylindrical lever lock engineering. Part of the legendary Sargent 11-Line Series, this lockset is purposefully built for "mission-critical" openings that face relentless daily use and physical abuse. While standard commercial locks struggle to meet baseline certifications, the 11G05 is in a class of its own, designed to outlast the building it is installed in. This unit comes equipped with a Sargent 6-pin LA Keyway cylinder, providing professional-grade security and easy integration into existing master key systems.

Unrivaled Mechanical Endurance

The Sargent 11-Line doesn't just meet ANSI/BHMA A156.2 Grade 1 standards—it obliterates them through superior American engineering and high-carbon steel components.

• 10 Million Cycle Performance: Independent testing proves this lock exceeds the Grade 1 cycle requirement by 12 TIMES, enduring over 10,000,000 cycles without failure.
• Extreme Torque Resistance: Locked levers are often the target of vandalism. The 11G05 withstands over 3,000 in/lbs of torque—3 times the Grade 1 requirement—protecting the internal chassis from "broomstick" or pipe-wrench attacks.
  
• Anti-Sag Technology: Unlike inferior locks that develop "lever droop" over time, the LL lever design features heavy-duty return springs to ensure the lever remains perfectly horizontal for decades.
• 10-Year Limited Warranty: Sargent offers a decade of protection with no service required to maintain the warranty, offering the lowest total cost of ownership in the industry.

Professional Office & Entry Function (ANSI F82)

The 05 Office Function provides the perfect balance of convenience and security for professional environments, allowing users to control access with a simple turn-button.

• 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 Versatility: Turning the interior button keeps the exterior lever locked until it is manually turned back to the unlocked position, allowing for "passage" or "restricted" modes.
• Automatic Unlocking: Rotating the interior lever or closing the door automatically releases the push-button (but not the turn-button), preventing accidental lockouts.
• Fail-Safe Egress: The inside lever is always free for immediate exit, ensuring 100% compliance with NFPA 101 Life Safety and ADA accessibility codes.
• Deadlocking Latchbolt: Includes a 1/2" throw stainless steel latch and an auxiliary deadlatch to prevent "shimming" or credit card manipulation.
