LOB ARES WS54 50/50 Profile Cylinder Brass Class 4 Key Security EN 1303

Product Overview

The LOB ARES WS54 50/50 cylinder is a double-sided brass profile cylinder designed for mortise lock integration, frequently used in both residential and commercial entry doors. Classified according to PN EN 1303:2015-07 standards, it achieves the highest grade for durability and corrosion resistance (class 6 and class C respectively), operating reliably over at least 100,000 cycles and within a temperature range of -20°C to +80°C. Approved for use in fire protection door assemblies, this cylinder is suitable for environments subject to demanding safety and technical requirements.

Its most differentiating feature is its class 4 key security rating, providing a minimum of 30,000 key differs. This reduces master key risks in large facilities and supports procurement requirements where key duplication control and combinatorial security are critical. Particularly suited for facility managers and institutional buyers overseeing multi-user access in office buildings, schools, or public infrastructure.
