The Mortise Lock That Adapts: ML2000 Series Multifunction Capability
Discover how the Corbin Russwin ML2000 Series mortise lock simplifies facility management with modular, reconfigurable functionality. Adapt to changing security and room needs without costly replacements.
In today’s commercial and institutional environments, flexibility isn’t optional—it’s essential. Security requirements change. Room functions evolve. Maintenance teams are expected to do more with less.
The Corbin Russwin ML2000 Series mortise lock is built to meet these demands head-on. With its modular design and robust construction, it delivers the versatility facilities need without sacrificing performance.
One Lockbody. Up to Twelve Functions.
The ML2000’s multifunction capability starts with a single lockbody that supports up to twelve different ANSI/BHMA functions—including storeroom, classroom, classroom intruder, and passage—through simple configuration changes.
Instead of replacing the entire lockset when an opening’s function changes, technicians can easily reconfigure the existing lockbody with alternate components. That saves time, reduces complexity, and eliminates unnecessary inventory.
The following chart uses the ML2054 function as the base/starting function with other functions configured from it.
