LOB ARES WS54 40/40 Euro Profile Cylinder Brass Fire Door Certified EN 1303

Product Overview

The LOB ARES WS54 40/40 Brass Euro Profile Cylinder is engineered for integration with mortise locks in commercial, industrial, and multi-family residential buildings. Rated to PN EN 1303:2015-07, it offers the highest grade of durability (class 6, over 100,000 cycles) and corrosion/temperature resistance (class C, -20°C to +80°C), and is permitted for use in fire-rated assemblies. B2B buyers benefit from its high-security key protection class 4, delivering a minimum of 30,000 unique key combinations for controlled access.

The primary differentiator of this variant is its certification for fire door assemblies, mitigating regulatory risks for large-scale projects where compliance is mandatory. This makes the WS54 model well-suited for procurement by facility managers, fire safety contractors, and OEM specifiers handling public buildings, hospitality, or institutional facilities where high durability and fire certification are required.
