Product Overview

The LOB ARES WS54 40/40 nickel cylinder is suitable for use with mortise locks in commercial, residential, and institutional buildings. It is classified under PN EN 1303:2015-07 and meets top-grade requirements for durability (class 6, minimum 100,000 cycles), corrosion resistance (class C, -20°C to +80°C temperature range), and key security (class 4, over 30,000 key combinations). This product is approved for installation in fire-rated door assemblies, supporting both safety and regulatory compliance for professional environments.

What distinguishes the WS54 40/40 model is its class C rating for maximum corrosion and temperature resistance, which minimizes maintenance risk and supports reliable operation in demanding settings such as high-traffic, indoor-outdoor, or variable climate locations. Facilities managers and bulk procurement buyers specifying components for public buildings, offices, or industrial facilities will find this cylinder particularly suitable due to its combination of fire approval, security grading, and environmental resilience.
