Abstract
A window assembly is described for installation in window openings having different thicknesses. A window frame having parallel side jambs, a header and a sill having inner and outer edges, and forming a rectangular opening is provided. C-shaped clamps are attached to the inner faces of the jambs, header and sill. The clamps include inwardly extending inner and outer side arms spaced at a given width, and an inner side. A rectangular extender frame is formed of four rectangular boards having lengths corresponding to the lengths of the frame jambs, header and sill. The extender frame is inserted into the clamps and moved relative to the window frame until the combined thickness of the extender frame and window frame corresponds to the thickness of the opening into which the window frame is to be mounted. Extender trim can be added to hide the clamps.
