ABUS X12 50G/40 Euro Cylinder SKG Class 6.D Nickel Thumbturn Patent Key System

Product Overview

The ABUS X12 50G/40 nickel-plated anti-burglary cylinder with thumbturn is a precision-engineered security cylinder designed for commercial, institutional, and high-standard residential applications. Certified to SKG, DIN 18252, DIN EN 1303, ITB class 6.D, and manufactured in accordance with ISO 9001, it offers advanced resistance against drilling, picking, and bumping, with fire-rated suitability for public buildings. The set includes 5 paracentric dimple keys and features an emergency function clutch allowing double-sided operation, even if a key is inserted on the inside.

Unlike standard cylinders, the ABUS X12 offers patent protection for the key profile until 2030, securing procurement against unauthorized duplication and providing compliance with projects requiring key control. This makes it particularly suited for access control system integration in corporate offices, schools, and public institutions, as well as for bulk specification in multi-tenant facilities where security regulations demand current patent protection and drill resistance.
