LOB ARES WG54 50g/55 Cylinder Lock with Knob Nickel EN 1303 Fire Rated Class C

Product Overview

The LOB ARES WG54 cylinder lock with knob is intended for use with mortise locks, primarily in commercial and residential doors requiring enhanced security and durability. Certified to PN EN 1303:2015-07, this model achieves class 6 for durability (over 100,000 cycles), class C for corrosion and temperature resistance, and class 4 for key security (over 30,000 unique key combinations). It is also approved for installation in fire-rated door assemblies.

Distinctive to the WG54 50g/55 variant is its highest corrosion and temperature resistance classification, allowing operation from -20°C to +80°C. This removes the risk associated with installations in harsh environments such as exterior doors, unheated warehouses, or high-traffic public facilities. Specification managers in fire safety projects and bulk procurement for commercial buildings will find this cylinder particularly suited for applications requiring resilience and regulatory compliance.
