LOB ARES WG54 30g/55 Cylinder Lock Insert Brass Thumbturn EN 1303 Class C

Product Overview

The LOB ARES WG54 30g/55 is a pin cylinder lock insert with a thumbturn, designed for collaboration with mortise locks in commercial and residential doors. Classified to PN EN 1303:2015-07, it features class 6 durability (over 100,000 cycles), class 4 key security (over 30,000 key combinations), and class C corrosion/temperature resistance for demanding environments. Approved for use in fire-rated door assemblies, it operates reliably in temperatures ranging from -20°C to +80°C.

Its most distinguishing feature is the compliance with the highest class C corrosion and temperature resistance under EN 1303, reducing maintenance risk for facility managers and ensuring long-term functionality even in exposed or challenging installations. This makes it particularly well-suited for building contractors, fire safety projects, and bulk procurement for institutional buildings where regulatory compliance and installation longevity are critical.
