This a basic mounting frame and 2- screw down clamps for the DNA20 or DNA30. You can adhere the frame to your case with epoxy or hot glue and then secure the DNA board in place with 4 - 1/4" Torx Thread Forming Screws for Plastic available at McMaster-Carr. There is no need to remove the fire button from the DNA board and this frame mounts the board face down to prevent any accidental activation of the on-board switches. There is a relief for the ribbon cable so you can place this in close proximity to the screen cradle of your choice. This pairs up very nicely with my new Screen Cradle and Clamp Set. The two small clamps are joined together with a cylinder that will need to be trimmed away before installation. Here is link to the stainless steel screws or the slightly cheaper option is to buy the zinc plated steel version of the screws.
