Also, each of the jamb legs and head piece has a second right angle flange leading outwardly at a right angle at a point forwardly of the rear edge and in a direction opposite from the first flange. A sill piece is used in combination with the jamb legs and head piece for completing a window frame, and this sill piece has a first flange leading downwardly at a right angle at a point rearwardly of its front edge and arranged to abut against the front surface of the roughed-in frame.
