It’s not hard to imagine what a door frame is. It’s the frame that supports a door. It has the threshold or sill at the bottom, and the header at the top. On either side are door jambs.
The door jamb on the same side as the doorknob and borehole is called the strike jamb, because it’s the part that the door ‘strikes’. The other side, where the hinges go, is called the hinge jamb.
The piece of hardware that the doorknob latch opens into is actually called the strike plate.
If you have an uncomplicated standard door, you use a flat jamb. Each of the two jambs have one piece of wood. They’re sturdy.
If you have an older home with walls that are less than plumb, or a wall with an irregular thickness, you may opt for a split jamb. The split jamb looks like a flat jamb, but each jamb is actually made of two pieces that fit together with tongue and groove. Split jambs have the advantage of being able to have the door casing pre-attached.
