Doors generally have at least one fixed handle, usually accompanied with a latch.
A typical "handle set" is composed of the exterior handle, escutcheon, an independent deadbolt, and the interior package (knob or lever).
On some doors the latch is incorporated into a hinged handle that releases when pulled on. Doorknob – A knob or lever on an axle that is rotated to release the bolt.
