DIERRE ATRA 197 Mortise Lock Dual System Left-Handed Lock Trap 6 Bolts

Product Overview

The DIERRE ATRA 197 mortise lock is designed for left-handed Dierre ASS03 doors opening inward, and features a dual locking system operated both by a cylinder and a lever key. Commonly used in residential and commercial settings requiring heightened security, this lock is built into the door leaf and incorporates six robust locking bolts, enhancing both protection and structural stability.

A distinguishing feature is the Lock Trap mechanism, which automatically secures the lock if the cylinder is removed, preventing unauthorized manipulation or forced entry.
