Sargent 28-10XG24 LL Entrance Function Cylindrical Lockset (Push Button)
Function Information:
The Sargent 28-10XG24 LL is a top-tier Grade 1 Cylindrical Lock engineered for high-security "Entrance or Office" (F82) applications. Part of the elite Sargent 10X Line, this lockset is purpose-built to survive high-traffic, high-abuse environments such as schools, hospitals, and government facilities. Unlike standard office locks, the 10XG24 features a robust pushbutton locking mechanism on the interior lever. When the button is depressed, the outside lever remains locked even after the door is closed, ensuring your workspace remains secure until manually unlocked by a key or the inside handle.
Heavy-Duty Security and Resilience
The 10XG24 is designed to provide "maximum resistance to vandalism." It is UL-verified to exceed 20 million cycles, providing a service life up to 20 times longer than standard Grade 1 locks. In physical attack testing, it withstands 3,100 in-lb of abusive torque and 1,600 lbs of offset pull, maintaining security where lesser hardware would fail. Its independent return springs ensure the linear LL lever stays perfectly horizontal, eliminating lever sag even after decades of constant use.
Reliable Operation in Real-World Conditions
Facility doors are rarely perfect, which is why the Sargent 10XG24 is engineered to handle 100lb of latch preload. This ensures the latch retracts smoothly even if the door is warped or the building has settled, preventing "latch bind" that often leads to lock failure. The non-handed design allows for easy installation on any door swing, while the innovative pushbutton is recessed to prevent damage from door stops or wall impacts.
Key Product Features
- Entrance/Office Function: Outside lever locked by interior pushbutton; unlocked by key outside or rotating the inside lever.
- Persistent Locking: Closing the door does not unlock the outside lever, providing consistent security for unoccupied offices.
- Extreme Cycle Life: UL-verified for 20 million cycles—the highest performance rating in the industry.
- Superior Vandal Resistance: Withstands over 100 vertical impacts, 20 times the requirements of ANSI/BHMA A156.2.
