The Sargent 70-RX-10XG37-LB-12V is a Grade 1 classroom function cylindrical lock built for high-traffic commercial and institutional openings where security and monitoring matter. It pairs the durable 10X Line chassis with an integrated Request to Exit (RX) switch, allowing the lock to signal access control systems when the lever is operated. Featuring the B lever on the L rose, this 12V electrified lockset comes with a 2-3/4" backset and a 4-7/8" strike. It uses a small format interchangeable core prep and ships less core, so you can key it into your existing SFIC system. This is an ideal choice for schools, offices, and healthcare facilities.
