500mm x 400mm Window Mount, with a centrally positioned, square 280mm x 280mm window.

Introducing the Pinnacle Square Picture Mounts, a range of high-quality, pre-cut mounts. With a smooth surface and white core, these mounts are excellent for framing your photography, whether for use in the home or as an exhibition entry. 

With a window of 280mm x 280mm, this size is the largest square possible using an A3 image. The aperture is positioned so that the mount has a slightly deeper base than the top.

As with all of our window mounts, we guillotine trim the mount board to 500mm x 400mm, before cutting the window, to ensure clean, accurate sizing. The window is cut using computer controlled cutters to ensure accurate and clean cut bevel windows. The central positions allows for either portrait or landscape images.

Aperture position:
60mm from left
60mm from right
95mm from top
125mm from bottom.
