Product Overview

The LOB ARES WA54 35/50 brass euro cylinder lock is designed for use with mortise locks in commercial, institutional, or residential buildings. Classified according to PN EN 1303:2015-07, it meets grade 6 for durability with a minimum of 100,000 lock/unlock cycles, and grade C for high corrosion and temperature resistance (operating from -20°C to +80°C). Fire door suitability is confirmed, allowing installation in assemblies requiring certified fire-protection hardware.
