LOB ARES WG54 Euro Cylinder 50g/45 with Knob Brass Key Security Class 4 Fire Rated

Product Overview

The LOB ARES WG54 50g/45 Euro profile cylinder with knob (brass) is designed for integration with mortise locks in commercial, residential, and institutional access installations. The cylinder is certified to PN EN 1303:2015-07 and meets the highest standard for mechanical endurance (Class 6, 100,000 cycles) as well as corrosion and temperature resistance (Class C, -20°C to +80°C), which makes it suitable for use even in demanding environments. Fire-door suitability expands its range of compliant applications, addressing strict safety requirements in modern projects.

Unlike generic cylinders, this SKU offers a security feature of key protection at Class 4, providing at least 30,000 unique key combinations, which significantly lowers key duplication risk in multi-user facilities. The integrated knob enables convenient interior access without a key, reducing operational delays and service calls. A strong choice for bulk procurement by facility managers specifying for fire-rated doors and multi-user properties where both security and durability are contractual priorities.
