WILKA 1400 K423 Double Cylinder 45/55 EN 1303 Class C Security Card Satin Nickel

Product Overview

The WILKA 1400 K423 45/55 double cylinder is a high-security profile door cylinder designed for demanding commercial and residential environments. It is tested and certified to EN 1303:2015 (classification 1 6 0 B 0 C 6 D), offering class C burglary resistance, making it suitable for fire-rated doors and applications requiring top-level security. Each cylinder is equipped with a paracentric keyway and 6 lever pin construction, with components made of hardened steel and brass with a nickel-plated finish for enhanced durability and corrosion resistance.

What sets this model apart is the mandatory authorization system for duplicate key cutting?keys can only be copied using the included security card at authorized service points. This feature dramatically reduces the risk of unauthorized duplicates, a critical concern for facility managers and administrators of sensitive sites. Ideal for bulk procurement in multi-apartment buildings, commercial projects, or facilities requiring strict access control and traceable key management.
