CE EN1634 Fire Door Hardware Supplier

What Is a Euro Mortise Lock?

A Euro mortise lock is a concealed locking mechanism that integrates directly into the door's internal structure through a precisely machined rectangular cavity. Manufactured in strict accordance with European DIN and EN dimensional standards, this lock architecture provides superior resistance to physical attack while maintaining a clean, unobstructed door surface.
Unlike surface-mounted cylindrical locks, the mortise design distributes force across the entire lock body, delivering significantly higher structural integrity. The standardized Euro-profile cylinder aperture enables seamless integration with master key hierarchies and advanced access control configurations — making it the preferred specification for architects and security consultants working on commercial-grade projects.
