WILKA 1400 K423 Euro Profile Cylinder 30/45mm Class C EN 1303 Black High Security

Product Overview

The WILKA 1400 K423 30/45 cylinder lock is designed for high-security door installations in commercial, institutional, and residential buildings requiring advanced protection. Certified to EN 1303:2015, class C, and approved for use in fire-rated doors, it features a 6-pin paracentric mechanism, hardened steel and brass pins with a nickel coating for increased durability, and resists corrosion at the highest rating level C. The lock comes pre-packed with three dimple cut keys and ensures over 100,000 tested operating cycles, meeting long-term durability requirements in demanding environments.

A defining advantage of this model is the combination of anti-picking mushroom pins and reinforced drill-resistant elements within both the core and housing, providing 5 to 10 minutes resistance against drilling, mechanical attacks, and forced extraction. This high-security profile is supported by coded key duplication controls?additional keys can only be obtained with an authorized security card issued with each lock. The WILKA 1400 K423 is particularly suitable for new construction, retrofit projects, or facility upgrades where rigorous access control and certification compliance are required.
