DIERRE ATRA 197 Mortise Lock Dual-System Euro Cylinder Lever Key Lock Trap Right

Product Overview

The DIERRE ATRA 197 mortise lock is designed for installation in right-handed Dierre ASS03 doors opening inward. This dual-system lock allows door securing via both a euro profile cylinder and a lever (pióro) key, suitable for use in residential and light commercial environments where enhanced security is required. The lock body incorporates six robust bolts, providing strong resistance to forced entry and maintaining door stability.

A distinguishing feature of the DIERRE ATRA 197 is its Lock Trap mechanism, which automatically blocks the lock if the cylinder is removed?an important safeguard against tampering and burglary attempts. This capability reduces security risks during maintenance or in scenarios where unauthorized cylinder access might occur. The lock is particularly recommended for residential apartment doors and property managers seeking to standardize advanced security solutions across multiple units.
