The Kinotehnik Spare Frame for LCDVF 4N is the same type of frame that's included with the LCDVF 4N viewfinder for the Nikon D800 / D800E. You can use it as a replacement for your existing frame or for an additional camera.
The frame is made of magnetic metal and housed in a plastic clip-on frame. The clip-on frame attaches to the camera's LCD the same way the camera's original screen protector does. The frame mounts and removes without any wear and tear, and no adhesive is used in mounting.
