Abstract: A door and window arrangement for hingedly mounting in the opening of a cab frame wherein a door frame is formed complementary to and fitting within the opening and having a first frame extending inward. A sub-assembly is formed having an outer frame with a second flange extending toward and in close proximity to the first flange. A gimp engaging both flanges joins the door frame and subassembly into a completed assembly. An inner frame defining a pair of tracks is fastened to the inside of the inner frame. A fixed pane of glass is sealed into the lower portion of one track and a movable pane of glass is mounted in a metal frame with a plastic slider affixed to vertical members of the metal frame positioned within the other track.
