Product Description
The Sargent 2870-10G37-LB-03 is a 10 line cylindrical lock with Classroom function in Bright Brass (US3/605). Outside lever locked until unlocked by key, relocks automatically when door closes. Inside always free. Grade 1 certified for heavy commercial use.
Ships prepped for a Small Format Interchangeable Core (SFIC) — the core is not included. Order your SFIC (Best-style) core separately to match your key system; it drops into the figure-8 housing with a control key for an instant rekey without removing the lock.
