01 / OVERVIEW

Overview

The C20 Series features a compact mortise lock case with a deadbolt mechanism, designed to provide dependable security where installation space is limited. The C2029 combines exterior key operation with an interior thumb turn that can retract the deadbolt but cannot project it.

This operating function distinguishes the C2029 from conventional deadlocks with a standard interior thumb turn. Designed for classroom and institutional applications, it offers a practical solution for doors requiring controlled exterior locking and convenient interior deadbolt retraction.

The series is designed in accordance with ANSI/BHMA A156.36 requirements for auxiliary locks.
