Lock
Masonry locks are architectural features that provide security to building occupants and restrict access to unauthorized personnel. Generally, they are composed of a mortise and tenon joint, which is created by cutting a groove in one stone and a projection in the other that fits securely into the groove. This joint is then reinforced with a locking pin, or a locking bar, and a latch. Masonry locks are a traditional and effective form of security, often used in historic buildings where the risk of forced entry is low.
