The Perimeter 1500 and Perimeter 2000 frames offer two different scales of the same frame and share a common function and feature set. These systems offer removable stops which allow installation from either the viewing or the projection side. The P1500 occupies just 2inches, front to back, to compactly fit any aperture. The framing system adds 1 ¾inches to the image area and works with any ¼inch or 3/8inch based rigid substrate — up to 10feet in width. P2000 is ideal for larger, half inch thick glass and measures 3 inches, front to back, while adding 2inches all around the image area. P2000 comfortably frames anything up to 29feet 11inches in width.
