This drawer was turned into a storage shelf in under five minutes, and that included mounting.
All that had to be done was add mounting hardware on back side and then hang. Leaving the door on the drawer made for a nice large top.
Once it was mounted we added a screw to the side for hanging. In under five minutes we had handy storage shelf. Depending on use you could also add a piece of wood in middle to add another shelf.
