What is a door jamb?

The jambs, also called the door “legs,” are the interior sides of a door frame—specifically the parts of the frame that hold the mounting hinges on one side and the strike plate for the latch on the other. 

Be careful not to confuse the jambs with other door frame parts, and specifically the door casing, which is what you call the wood that surrounds the door frame, colloquially called the door trim.

The jamb is only part of a door frame. If you want to replace your door jamb, you should purchase a door frame set, which includes all the parts you need to build a whole new frame. In addition to the jamb, here are the other components of a door frame:head , still,door stop,weatherstriping, jamb casing.
