Corbin Russwin DL2217-KEYED Cylindrical Deadlock Classroom Function with Single Cylinder Keyed Operation

Commercial-Grade Cylindrical Deadlock for Classroom Security Applications

The Corbin Russwin DL2217-KEYED is a commercial-grade cylindrical deadlock from the DL2200 Series, engineered for classroom function in demanding institutional environments. Designed for standard 1-3/4" (44mm) door thickness with a standard 2-3/4" (70mm) backset (optional 2-3/8" / 60mm available), this non-handed deadlock features a 1" throw solid steel deadbolt with a hardened, free spinning steel pin insert for superior forced-entry resistance. The unit operates by key outside and by thumbturn inside, with the thumbturn capable of retracting but not projecting the deadbolt, making it ideal for controlled-access classroom environments. The front plate is wrought brass or bronze measuring 2-1/4" (57mm) x 1-1/8" (29mm), and the standard strike measures 2-3/4" (70mm) x 1-1/8" (29mm).
