Understanding Doorknobs: Types, Materials, and Features
A doorknob is a knob or handle that is attached to the door and used to open or close it. It is typically located on the exterior of the door and can be turned to unlock or lock the door, depending on the type of doorknob and the locking mechanism it is connected to. Doorknobs come in a variety of styles and materials, such as brass, bronze, stainless steel, and plastic, and can be decorative or functional in nature. Some doorknobs also have additional features, such as keyholes, deadbolts, or lever handles, which can provide additional security or convenience.
