WILKA 1405 K423 Cylinder Insert EN 1303 Class C Nickel Matt 60g/55 High Security

Product Overview

The WILKA 1405 K423 cylinder insert, in a 60g/55 nickel matt finish, is a high-security double-sided profile cylinder designed for commercial and residential doors requiring advanced protection. Certified to EN 1303:2015 and burglary resistance class C (WQ-ITB), this product is suitable for use in doors with rigorous access control requirements and fire resistance specifications. Each insert comes with three profiled cut keys and features a 6-pin mechanism with both brass and hardened steel pins for enhanced durability.

A critical differentiator of the WILKA 1405 K423 is its paracentric key profile combined with anti-picking and anti-drilling protections, offering the highest rated resistance to forced entry and manipulation as per EN 1303 level 6. This eliminates the procurement risk associated with lower-tier cylinders in high-security projects and simplifies key management through the included security card. The product is particularly suited for procurement in high-risk commercial facilities, institutional buildings, and fire-rated door installations demanding certified and traceable security hardware.
