Understanding Door Lock Assemblies
A Door Lock Assembly is a complete mechanical or electronic system that secures a door and controls access to a space. It consists of multiple components working together to provide security and functionality.
Types of Door Lock Assemblies
Mortise Lock Assembly
A sophisticated locking system that fits into a pocket (mortise) cut into the door's edge. These assemblies include the lock body, strike plate, trim, and handles. Known for their durability and security, mortise locks are common in commercial buildings and high-end residential properties.
Cylindrical Lock Assembly
Also known as bored locks, these are the most common type in residential settings. The assembly includes a keyed cylinder, latch mechanism, handles/knobs, and strike plate. They're installed through cylindrical holes bored through the door face and edge.
Electronic Lock Assembly
A modern security solution that combines mechanical components with electronic access control. These assemblies may include keypads, card readers, or biometric scanners, along with traditional mechanical components. They offer enhanced security features like audit trails and programmable access.
Deadbolt Lock Assembly
A high-security lock assembly that includes a solid metal bolt that extends deep into the door frame. The assembly consists of the deadbolt mechanism, strike plate, and keyed cylinder or thumb turn. Often used in conjunction with other lock types for additional security.
Panic/Exit Device Assembly
Designed for emergency exits in commercial buildings, these assemblies include a push bar mechanism, latch, and outside trim. They allow quick egress while maintaining security from the outside.
Benefits of Quality Door Lock Assemblies
- Enhanced security for your property
- Reliable access control
- Durability and long-term performance
- Compliance with building codes and safety regulations
- Peace of mind for property owners and occupants
Choosing the right door lock assembly is crucial for your security needs. Consider factors like intended use, security requirements, and building codes when selecting a lock assembly.
