Sargent 28-10XG08 LL Communicating Classroom Lockset
Function Information:
The Sargent 28-10XG08 LL is an industrial-grade Grade 1 Cylindrical Lock designed for high-security "communicating" applications where a blank plate is required on one side. Engineered as part of the Sargent 10X Line, this lockset is purpose-built for spaces that require keyed access from one side only, with the ability to lock or unlock that lever via key. Whether managing access between secure zones or protecting specialized storage, the 10XG08 delivers the "durability, strength, and performance" required for the most demanding institutional environments.
Specialized Communicating Functionality
The 10XG08 Communicating Classroom (F113) function is distinct: it features a functional LL lever on one side and a blank plate on the other. The key on the active side locks or unlocks the lever, providing controlled access without a redundant handle on the opposite side. This configuration is essential for security-sensitive areas where unauthorized entry from one side must be physically impossible. Equipped with the freewheeling lever option, the handle rotates freely when locked to deflect force and prevent vandalism.
Industry-Leading Durability and Strength
Tested to an incredible 20 million cycles, the Sargent 10X line exceeds ANSI/BHMA A156.2 Grade 1 requirements by up to 20 times. This lockset is nearly impervious to physical attack, withstanding 3,100 in-lb of abusive torque and 1,600 lbs of offset lever pull. Its patented adjustable push/turn button and independent return springs ensure that the linear LL lever stays perfectly level, eliminating lever sag even after decades of high-frequency use in schools, hospitals, and government facilities.
