LOB ARES WS54 40/40 Cylinder Insert Brass EN 1303 Fire Door Certified

Product Overview

The LOB ARES WS54 40/40 brass cylinder insert is designed for integration with mortise locks in commercial, institutional, and multi-dwelling residential buildings. Classified according to PN EN 1303: 2015-07, it meets durability class 6 (at least 100,000 cycles) and security class 4 (minimum 30,000 key differs), with the highest corrosion and temperature resistance class C (-20°C to +80°C). The product is approved for use in fire door assemblies, meeting stringent safety requirements for regulated facilities.

A distinguishing feature of this model is its certification for use in fire-resistant door sets, directly addressing compliance risks on projects that require certified hardware. This eliminates uncertainty for B2B buyers sourcing for public buildings, commercial infrastructure, or any fire-protected environments. It is highly recommended for procurement teams servicing contractor, facility management, or OEM projects where certified fire protection hardware is mandatory.
