We are having trouble figuring how to attach the drawer fronts to these soft close drawer trays. We know how to get the rods attached to the backs of the drawer fronts but not how they then fit into the slots shown in the picture. If anyone knows of a website which give an installation guide it would be appreciated. The Company who we bought the Cabinets from do not offer an customer service. This is probably because we chose not to have their fitting service. Many thanks.
