Product Overview

The LOB ARES WA54 40/55 Euro profile cylinder is designed for integration with mortise locks in commercial and residential doors. Certified according to PN EN 1303:2015-07, it achieves durability class 6 (minimum 100,000 cycles), key security class 4 (at least 30,000 key variations), and corrosion/temperature resistance class C for enhanced performance from -20°C to +80°C. Approved for use in fire-resistant door assemblies, it supports strict safety and building code requirements in public, office, or multi-family environments.

Unlike standard cylinders, the WA54 model stands out with its high key security class (class 4, 30,000 combinations), minimizing the risk of unauthorized duplication across large or sensitive installations. This makes it an effective choice for institutional buyers and bulk orders where system integrity and controlled access are essential, such as facilities management, educational campuses, or fire protection projects.
