Mortise locks are known for their strength and advanced security features. The Corbin Russwin ML2000 is a widely used Grade 1 mortise lock designed for demanding commercial environments. Choosing the correct lock function ensures the lock provides the appropriate level of security and usability.
Understanding Mortise Lock Functions
Unlike cylindrical locks, mortise locks contain complex internal mechanisms that allow multiple locking configurations. These functions determine how the latch and deadbolt operate and how occupants interact with the door.
Common ML2000 functions include classroom, office, entry, and storeroom configurations.
Classroom Function
The ML2055 Classroom functions allow the outside lever to be locked or unlocked with a key while the inside lever always permits exit. This design ensures that rooms can be secured from the hallway without trapping occupants inside.
Classroom functions are commonly used in schools, lecture halls, and training rooms.
Office Function
The ML2051 Office functions allow the outside lever to be locked from the inside using a push button or thumbturn. This makes them suitable for private offices where occupants may occasionally require privacy.
Storeroom Function
The ML2057 Storeroom functions keep the outside lever locked at all times. Entry requires a key, ensuring that only authorized personnel can access the space.
These locks are commonly installed on storage rooms, maintenance areas, and supply closets.
Entry Function
The ML2051 Entry functions allow the outside lever to be locked or unlocked using a key while the inside lever remains free for exit.
This configuration is frequently used on main office entrances and commercial building doors.
Selecting the Best Function
When choosing the correct ML2000 function, consider:
-
Security requirements
-
Door usage frequency
-
Occupant safety and egress requirements
-
Building code compliance
By selecting the correct configuration, facilities can ensure both security and operational efficiency.
