WILKA 1400 30/55 + 1405 30g/55 Cylinder Set EN 1303 Class C Knob Keyed Alike Nickel

Product Overview

The WILKA Cylinder Set 1400 30/55 + 1405 30g/55 with knob is a double-cylinder lock kit featuring one standard and one knob cylinder keyed alike, finished in matt nickel. Certified to EN 1303:2015, these cylinders are engineered for high-security applications in residential or commercial buildings, particularly where fire-rated doors or doors requiring Class C burglary resistance are mandated. The cylinders provide top corrosion resistance (Class C) and durability (over 100,000 cycles tested), making them suitable for medium- to high-traffic environments.

A standout feature of this SKU is its security level: the paracentric key profile and a combination of mushroom pins, hardened steel inserts, and anti-drill construction achieve the highest anti-burglary rating (EN 1303 class D/6/WQ-ITB Class C). This minimizes procurement risk where manipulation/picking and physical attack resistance are critical, and ensures compliance for specification-driven tenders. Ideal for bulk procurement by property managers, facility maintenance companies, or fire door OEMs requiring secure, compliant master-keyed solutions.
