I wonder if anyone knows what this item is called? I removed it from underneath the drawer on my office desk. I have upcycled the drawer by removing the front panel - now I can use it as a keyboard tray 😀 But I had to remove this piece as well, which isn't ideal as it provides stability. It went under the drawer from back to front. I would like to install something similar from left to right, to provide the stability but I will need a bigger size. Does anyone know what this is called please? Or of any other product that would serve this purpose?
