DIERRE ATRA 7112 Mortise Lock Four Bolts Bit Key Right-Handed Lock Trap

Product Overview

The DIERRE ATRA 7112 single-system mortise lock is designed for inward-opening right-handed Dierre ASS05 doors in residential or commercial settings. It is operated by a bit key and secures the door with four solid locking bolts for enhanced stability and physical protection against forced entry attempts.

A distinguishing feature is the Lock Trap system, which automatically immobilizes the lock mechanism if the bit cylinder module is removed. This reduces unauthorized tampering and significantly limits security risks during maintenance or attempted manipulations. The ATRA 7112 is particularly suited for OEM door manufacturers and security door installers specifying robust, tamper-resistant locking solutions for high-traffic entrances.
