DIERRE ATRA 7111 Mortise Lock Single-System Lever Key Left-Hand Lock Trap

Product Overview

The DIERRE ATRA 7111 is a mortise lock intended for use with Dierre ASS05 inward-opening doors, specifically adapted for left-hand door leaf installation in residential or commercial settings. It features a single-system design and is operated via a lever (piórowy) key, delivering solid mechanical locking. Four robust steel bolts are integrated to enhance security and reinforce door stability, making it suitable for environments requiring reliable access control.

A distinguishing feature of this model is the Lock Trap mechanism, which automatically immobilizes the lock if the cylinder module is removed. This reduces tampering risk and safeguards property against forced entry or manipulation during maintenance. Facility managers and security contractors seeking robust internal door protection will find this lock particularly suited for new-build or retrofit projects where cylinder removal protection is a procurement priority.
