While different types of door handles are designed with unique components, the average handle has basic components. For instance, in addition to the knob top, which is the large knob that you would actually grab hold of to turn, handles are made with a spindle, shank, and knob rose. The knob rose is a round washer or plate used to form a socket. This piece is adapted so it can be attached to the actual door. Then, there is that spindle, which is the thin piece to which the handle attaches. The shank is the stem that projects from the door handle. Within the shank is a hole in which the spindle would be placed. For functionality, the door handle would be attached so the metal shaft can turn the latch to open the door.

The placement of the handle is generally where it will provide an optimal mechanical advantage; most doors operating as second class levers. Doors with centre pulls or rings, or a pivot point in a location other than one edge of the door, use first or third class lever principles. Depictions of door handles in paintings dating to the first century CE are centrally placed hinged rings. The modern door knocker is a vestige of this style of primitive door handle. Doors were typically secured by bars and brackets to prevent them from being opened by either intent or accident.
