Abstract: A window display frame having a top panel, a bottom panel and two side panels. Each panel has an inner surface defining a channel for placement of the replacement window, an outer surface, and two ends. Each side panel has a longitudinal groove extending from each end along the center of the outer surface to an end point, and a bore located adjacent each end point. The bore preferably has a depth that is greater than the depth of the groove. There are four L-shaped corner brackets mounted one on each end of the top and bottom panels. Each corner bracket comprises two legs, an inner surface, an outer surface and inwardly flanged edges. Each end of the top and bottom panels is attached to and fits snugly into the inner surface of one leg of a corner bracket between the flanged edges. The free leg of each corner bracket can then be used for attachment to a side panel to complete the frame. The free leg of each corner panel has a protrusion located on the inner surface.

Abstract: A display case for a replacement window, comprising a case assembly and frame member. The case assembly has a front panel and a rear panel hingedly connected to each other near their top edges, and having an inwardly directed flange connected to their side edges. The frame member secures a replacement window therein and is slidably inserted within the case assembly. The frame member comprises two side sections, a top section and a bottom section. Each side section has at least one longitudinally-extending channel on its external surface for sliding engagement with a flange on the case assembly. The case assembly has means for preventing opening of the hinged connection beyond a predetermined maximum point. There is a plank attached to said bottom section of the frame and extending along its length. The plank has outwardly beveled longitudinal edges so as to create a groove between the bottom section of the frame and the bottom of each beveled edge.
