Sargent 28-10XG38 LL Classroom Security Lockset
Function Information:
The Sargent 28-10XG38 LL is the gold standard for Classroom Security (F110), specifically engineered to provide rapid intruder lockdown capabilities. Part of the elite Sargent 10X Line, this Grade 1 Cylindrical Lock is designed for the high-abuse environments of K-12 schools, universities, and government institutions. The G38 function allows the outside lever to be locked or unlocked by key from either side of the door, meaning a teacher can secure the classroom from the inside during an emergency without stepping into a potentially dangerous corridor.
Advanced "Intruder" Safety Features
Security and speed are paramount in the 10XG38. It features a double cylinder design where the inside cylinder controls the locking status of the exterior handle. To eliminate guesswork during high-stress situations, a visual lock indicator is provided on the inside rose as a standard feature, giving staff immediate confirmation that the door is secured. Despite the exterior being locked, the inside lever always remains operative, ensuring that life-safety egress is never compromised.
Unrivaled Durability and Vandal Resistance
The Sargent 10X line is built to survive where others fail. While standard Grade 1 locks are tested to 1 million cycles, the 10X is UL-verified to exceed 20 million cycles. It is engineered to withstand 3,100 in-lb of abusive torque (2.6x the industry requirement) and 1,600 lbs of offset lever pull. Its patented design handles up to 100 vertical impacts, providing 20 times the vandal resistance of ordinary locks. Even with 100 lbs of latch preload, the deadlocking latch retracts smoothly, making it ideal for warped doors or high-traffic areas.
