Glass sliding closet door replacement part

Hi,

I need a replacement piece for the bottom of a glass sliding door. There is not information about the type of doors these are other than they are home decor innovations along with cleaning instructions. This piece seems to provide the tension to keep the frame around the entire piece of glass on appropriately. If I'm looking at the door from the back (inside the closet) I am missing the bottom, left piece. I hope this provides an adequate description. I included photos of the top and bottom pieces to help identify.
