A door mortise handle is a type of door handle that is designed to fit into a mortise, or recessed, pocket in the door. The handle is typically a single unit that is mounted on the door with screws. It usually consists of two parts: the handle itself, which is attached to the door, and a locking mechanism, which is embedded in the door. The handle is usually made of metal or plastic and is designed to provide a secure grip. The locking mechanism may be a simple latch, or it may feature a more complex lock.
