ABUS X12 40G/55 High Security Euro Cylinder Nickel SKG Class 6.D with Knob

Product Overview

ABUS X12 40G/55 Antiburglar Cylinder with knob is a high-security euro profile cylinder lock, designed for modern commercial and institutional environments requiring top-tier access protection. Certified to DIN 18252, DIN EN 1303, SKG, and class 6.D fire resistance (ITB), it is suited for doors in public buildings, high-traffic zones, and facilities with strict security compliance demands. The cylinder features a nickel exterior and comes with five paracentric dimple keys as standard for secure controlled access.

The distinguishing asset of this cylinder is its patented profile protected until 2030, combined with a unique horizontal keyway and 12 hardened steel pins against drilling. This dramatically reduces procurement risk of unauthorized key duplication and manipulative attacks (drilling, picking, bumping), providing confidence to those specifying master key or keyed-alike systems in high-responsibility installations. Particularly recommended for institutional buyers, facility managers, and building contractors requiring certified, non-copyable key systems and quick integration with anti-burglar escutcheons.
