Pre-cut Pinnacle Black white core picture window mounts with an aperture to fit an A4 image - actual size 280x190mm. As with all of our window mounts we guillotine trim the mount board to 500x400mm, before cutting the window, to ensure clean accurate sizing, after which we cut the windows using computer controlled cutters to ensure high quality, accurate and clean cut bevel windows. These are centrally positioned to allow for either portrait, or landscape images.
