ABSTRACT:
A vinyl window frame has an accessory groove which is covered by a removable strip. When the groove is uncovered, it opens at an exposed face of the window frame. The frame includes first and second regions of weakness which facilitate removal of the strip. The first region of weakness is provided at the inside surface without penetrating through to the outside surface of the strip and the second region of weakness is provided along a side edge of the frame such that neither region of weakness is visible at the exposed face of the window frame.
