Mortise locks are generally regarded as which type of security device?

Mortise locks are typically classified as medium security locks due to their design, construction, and the level of security they provide. Mortise locks are installed into a mortise, or pocket, in the door, which allows for a larger and more secure locking mechanism compared to cylindrical locks. They often feature a deadbolt, which adds an extra level of security against unauthorized access.

While they are more secure than many low security locking devices, mortise locks do not usually reach the high security specifications that are required for locks that stand up to more sophisticated attacks, such as picking, drilling, or forced entry. High security locks often utilize advanced technologies, stronger materials, and features like restricted keyways to provide enhanced protection. Therefore, the designation of mortise locks as medium security reflects their balance of convenience, durability, and security in typical residential and commercial applications.
