  Door handles are a type of hardware used to open and close doors. They come in a variety of shapes, sizes, and materials, and are typically mounted on the surface of a door using screws or other fasteners. Door handles are often composed of two main parts: the handle or knob, and the latch mechanism. The handle or knob is the part of the door handle that is gripped by the hand to open or close the door, while the latch mechanism is the component that secures the door in place when it is closed. There are several types of door handles, including lever handles, knob handles, pull handles, and thumbturn handles. Lever handles are the most common type of door handle and are often used in commercial settings. Knob handles are typically found on interior doors in residential settings. Pull handles are often used on sliding doors, such as those found on closets or showers. Thumbturn handles are commonly used on bathroom doors and have a thumbturn mechanism that allows the door to be locked
