Sargent 28-10XG16 LL Public Entry or Classroom Security Function
Function Information: 
The Sargent 28-10XG16 LL is a high-performance Grade 1 Cylindrical Lock engineered for mission-critical security. Designed for the Classroom Security/Public Entrance (F88) function, this double-cylinder lockset allows the outside lever to be locked or unlocked by key from either side. This "Intruder" capability is a vital life-safety feature, enabling teachers or staff to lock down a room from the inside without ever stepping into a hallway. As a cornerstone of the Sargent 10X Line, it is built to endure the most rigorous institutional environments, outperforming standard hardware by up to 20 times.
Elite Lockdown Security & Vandal Resistance
The 10XG16 is the ultimate choice for facility managers prioritizing safety and durability. It features a unique double-cylinder design where the inside cylinder provides immediate control over the exterior handle's status. For added security, a visual lock indicator on the inside rose comes standard, providing at-a-glance confirmation that the door is secured. To thwart physical attacks, the lock resists over 3,100 in-lb of torque and 1,600 lbs of offset pull, while the freewheeling lever prevents vandals from forcing the mechanism.
Proven Performance Beyond Grade 1
Tested to an industry-shattering 20 million cycles, the Sargent 28-10XG16 is UL-verified to last decades in high-traffic schools, hospitals, and government offices. It is designed to function perfectly even under 100lb of latch preload, ensuring reliable operation on warped doors or those with heavy weatherstripping. The ergonomic LL linear lever meets all ADA accessibility standards, and the lock is UL/cUL Listed for use on 3-hour fire doors.
