ABUS X12 55G/45 Knob Cylinder Anti-Burglary Nickel SKG Emergency Function ITB 6.D

Product Overview

The ABUS X12 55G/45 nickel-plated anti-burglary cylinder with knob is a mechanical locking insert designed for doors in commercial and public buildings. Featuring German engineering and equipped with five dimple keys, it is certified to SKG, DIN 18252, and DIN EN 1303 standards, as well as fire-resistance (ITB class 6.D). It offers advanced protection against drilling, picking, bumping, and unauthorized key duplication thanks to its patented system (protected until 2030) and additional security pin.

What distinguishes this ABUS X12 model is its emergency (double-clutch) function, allowing a key to operate the lock from the outside even if a key is inserted from the inside. This eliminates the risk of lockouts and ensures critical access for facility managers and emergency personnel. It is particularly suited for bulk procurement in high-traffic public buildings or multi-tenant commercial properties where compliance with both burglary resistance and fire safety certifications is required.
