Description
Mortise locks are the gold standard of commercial security, featuring a heavy-duty lock body installed deep inside a pocket (mortise) cut into the door's edge. This embedded design makes them far more resistant to forced entry, prying, and tampering than surface-mounted locks. Known for their superior durability and longevity, mortise locks offer unparalleled security and versatility for high-traffic and high-security applications.
One of the key advantages of a mortise lock is serviceability. If internal components wear or are damaged over time, mortise locks are easier to repair or rekey without replacing the entire lockset, unlike most cylindrical leversets. Mortise locks are available in functions similar to leversets—including Classroom, Entry, Passage, and Privacy—allowing you to match your security needs without sacrificing performance. When ordered with a CDF door, your mortise lock can be factory-prepped for proper fit and installation, helping streamline your project and reduce jobsite labor.
Features & Benefits of Mortise Locks
Choose your mortise locks for light or standard-duty commercial doors. You'll get two operating keys with each lock or lever set. Mortise commercial door locks work for several standard door types, such as
- Passage
- Exit
- Privacy
- Office
- Entry
- Storeroom
Note that the lock chassis on each mortise door lockset includes heavy-gauge steel with zinc dichromate for corrosion resistance, making it the lock of choice for exterior applications. The lever is made with zinc and a combination of brass, bronze and stainless steel.
Mortise Locksets vs. Cylindrical Door Locks
While both mortise locksets and cylinder door locks are suitable for commercial use, cylindrical locks are also frequently used in residential doors. In fact, cylindrical locks are the most common type of door lock for all uses. Mortise locksets have the advantage of being more durable and offering a higher degree of security, two characteristics that make them highly suitable for commercial applications.

Mortise locks are recommended for high-traffic commercial areas where doors are opened and closed frequently throughout the day. They are commonly used in schools, restaurants, shopping malls, and public restroom doors, as well as other spaces with constant foot traffic. Their heavy-duty construction makes them ideal for environments that demand long-term durability and reliable performance.
Yes. Mortise locks can be integrated with access control systems through the use of an electric strike. The electric strike works in conjunction with an external device—such as a key card reader, keypad, or Wi-Fi–enabled access reader—which triggers the strike to allow entry. This setup allows mortise locks to support electronic access control while maintaining mechanical security.
