Abstract: A window shade system comprises a covering for the architectural opening, a pole on which the covering is wound, and a window frame mounting assembly. The window frame mounting assembly comprises a pair or bracket assemblies, which support the pole, one on each side of the opening. In one embodiment, the bracket assembly comprises a two-piece, three-way mounting unit comprising a first piece, and a second piece configured to mate with the first piece when the unit is positioned in or adjacent the opening. The second piece, which includes a hook to support an end of the pole, can be assembled in three (3) different configurations to achieve a custom mount with respect to the architectural opening (and the facing wall). In particular, and depending on the positioning of the first piece, the mounting unit is positioned to the front side, inner, or outer edges of an architectural frame or to the adjacent facing wall.
