Abstract: A building frame structure for a building opening and wedge shim structure for accurately plumbing and locating the frame, such as a door frame or window frame in a doorway opening or window opening, respectively, of a building. The wedge shim structure includes a plurality of shims placed about the frame in plumbed hung frame relationship. Each shim has a first wedge shim part fastened on the frame and a second wedge shim part slidably mountable on the first part for adjustably closing the space between the frame and the studding around the opening for placing a door or window structure in the doorway or window opening. This requires placing a level on the second wedge part of each shim to provide a plumb vertical frame wall on which to hang to door or slidably mount a window. This novel arrangement also provides for a shimming and plumbing method for attaching a door or window in plumb relation with the building opening.
