I actually purchased these items to use for a sliding spice rack but in the end didn't use them. I do think that they will work for what you are trying to do. They are heavy duty and it wasn't an issue mounting side rails onto them at all. The only thing to consider is that the drawer slides will need to be fastened on to the brackets with small bolts and nuts and that will leave the bolt ends protruding from the back. You may consider fastening a thin strip of wood to the backside of the bracket that faces the open side of the cabinet shelf for a cleaner look.
