Corbin Russwin DL3017 Grade 1 Cylindrical Deadlock, Classroom Function

Corbin Russwin DL3017-KEYED Cylindrical Deadlock with Classroom Function, Single Cylinder, Field Reversible

Commercial-Grade Cylindrical Deadlock for Classroom and Institutional Security

The Corbin Russwin DL3017-KEYED is a heavy-duty cylindrical deadlock from the DL3000 Series, engineered for classroom function in demanding commercial environments. Operated by key from outside and by thumbturn from inside — with the thumbturn designed to retract but not project the deadbolt — this lock delivers reliable one-way control ideal for educational and institutional settings. The unit accommodates door thicknesses from 1-3/4" (44mm) to 2-1/4" (57mm) and features a standard backset of 2-3/4" (70mm), with an optional 2-3/8" (60mm) backset available. The deadbolt provides a 1" (25mm) throw measuring 5/8" (16mm) wide by 3/4" (19mm) high, constructed with a zinc diecast hardened steel insert for superior resistance to forced entry. ANSI/BHMA E0170 Series compliant, this lock meets the rigorous standards expected of commercial-grade door hardware.
