jambs

Vertical sides of frames

Jambs are the vertical side pieces of a door or window frame—the parts you might lean against or grab when standing in a doorway.

The term extends to similar vertical supports in fireplaces and other architectural openings.

When installing a door, carpenters must ensure the jambs are plumb and properly shimmed.

The old house had ornately carved door jambs throughout.
