Sargent 70-RX-10XG37-LND-12V Classroom Function Cylindrical Lock, Request to Exit, L Rose, ND Lever, 2-3/4" Backset, 4-7/8" Strike, Small Format Interchangeable, Furnished Less Core, Grade 1

The Sargent 70-RX-10XG37-LND-12V is a Grade 1 classroom function cylindrical lock built for demanding commercial and institutional openings. It combines the durable 10X Line chassis with a Request-to-Exit (RX) switch, allowing the lock to signal an access control or monitoring system when the lever is operated from the secure side. This model features the LND lever on an L rose and accepts a small format interchangeable core, though it is furnished less core so you can key it into an existing system. With a 2-3/4" backset and 4-7/8" strike, it is ready for standard door prep and 12V operation.
