LOB ARES WJ54 9/50 Euro Cylinder Lock Class C Nickel EN 1303 Fire Door Approved

Product Overview

The LOB ARES WJ54 9/50 nickel euro cylinder lock is intended for integration with mortise locks in internal or external doors. Certified according to PN EN 1303:2015-07, it achieves class 6 for durability (guaranteed for at least 100,000 cycles), class 4 for high key security (minimum 30,000 key differs), and class C for maximum resistance to corrosion and operating temperatures from -20°C to +80°C. Approved for use in fire-rated assemblies, it addresses both residential and commercial door specification requirements where certification is critical.

Unlike generic cylinders, this model's class C rating delivers the highest corrosion and temperature protection, substantially reducing service risks in high-use, exposed, or mission-critical facilities. Its high key differs and fire-door approval make it particularly suitable for specification-driven B2B projects such as public buildings, hotels, or bulk procurement for property management where standards compliance is mandatory.
