This screen clamp goes between the DNA200 board and is designed to have the board rest on it. While the DNA200 is screwed down it will apply pressure to the screen and keep it in the screen cutout on the mod. My suggestion is to place the screen in the mod and then place the clamp in before resting the DNA200 in the mod to screw down. Note: This is designed to work with the screen recess on my DNA200 enclosure designs. It is not inteneded as a universal mount for all enclosures but it may be adaptable to an enclosure that does not have a screen recess by sanding down about .45mm on the bottom.
