Abstract: A low cost drainage arrangement is described for closure frames which arrangement does not increase the overall size of the frames. Between the inner and exterior track recesses a passageway is provided to prevent the accumulation of water in the inner recess. The outer recess has at least one slot adjacent to the side of the frame and laterally displaced from the passageway. An exterior panel frame member for a screening panel or the like covers and shields the exterior portion of the passageway for free drainage during adverse weather conditions.
