This is a combo pack of the Rectangle with Filet Edges Screen Cradle and the Screen and DNA Clamp. You can save some money buying both parts together but are more limited in the material choices. The required opening in the case is 33.2 x 12.2 millimeters. The screen opening is 19.5 x 7 millimeters. All testing is complete and this is the final redesign of the screen cradles and the clamping system. The clamps work very well and allow you to secure your screen and chip to the cradle without the use of epoxy on the expensive electronics!
