This door panel is fabulous! The colors are so rich. The background glass is especially beautiful with a mix of blue purple and green. It is framed in zinc and again framed in a white wooden 2" diameter frame which brings the total dimentions to 39 and1/2" x 24".The wooden frame has 4 screw holes, 2 at the top of the frame and 2 at the bottom. The panel is designed to mount on the inside of the front door of your home. Is is currently hanging on my front door and I get lots of wow's from the view inside or out. At night it is lit from the inside with a small halogen light.
