The Mortise Lock That Adapts: ML2000 Series Multifunction Capability
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.
| Function No. | Type | Function Description | Extra Parts Required |
|---|---|---|---|
| ML2054 (F04) | Entrance / Office | • Latch by grip both sides • Outside grip locks/unlocks via thumbturn • Key unlocks when outside is locked • Inside always free |

Streamlined Maintenance and Inventory
The benefits go beyond the opening itself. By standardizing on the ML2000 Series platform, facility teams can:
- Minimize the number of lockbodies required to support various door functions
- Reduce training needs for service technicians
- Speed up response times when functions need to change or be restored
Whether you’re managing a school campus with evolving safety protocols or a healthcare facility adapting spaces for patient needs, the ML2000 Series simplifies the process.
Performance You Can Count On
Corbin Russwin is known for manufacturing durable, high-traffic hardware—and the ML2000 Series is no exception. Its heavy-duty mortise construction meets demanding performance standards, making it ideal for institutions that can’t afford failures or inconsistencies.
Every component is engineered for long-term reliability, giving you peace of mind that your openings will perform as expected, year after year.
The Smarter Standard for Mortise Locks
The ML2000 Series isn’t just another mortise lock—it’s a smarter standard. Its multifunction capability gives security professionals and facility managers the freedom to adapt without the burden of full-scale replacements.
With one lockbody and multiple configuration options, it delivers what today’s buildings need: flexibility, reliability, and reduced total cost of ownership.
