It's a holder for your HautePad (assuming you have a G16).
IDK, look at the picture and the title, if you can't tell what it is or why it does what it does at that point, then I don't know anything I write here is gonna help.
it's not perfect, but it fits the pad pretty snugly and it no longer moves around my drawer when I open and close it. Works for me!
