Abstract: As installation clip for use in supporting a window, such as a mulled window, during installation in a building wall opening, and reinforcing the window after installation against the pressures of wind or the like. The installation clip is of unitary construction with a generally flat base portion, and a set of counterextending, raised tab portions projecting upwardly and outwardly from one side of the base portion. The height and width of the raised tab portions are selected to conform substantially to the dimensions of a recess in the bottom frame member of the window with which the clip is to be used. The installation clip is mounted to the sill structure of the building wall opening, with its tab portions facing into the center of the opening, and the window is inserted into the opening onto the mounted clip. The raised tab portions of the clip engage in the recess in the window bottom frame, and hold the window in place while it is permanently secured in the opening by conventional means.
