Review on Houseables Picture Hanger Kit - Mirror Hanging Hardware, French Cleat, 3 Pair, 6 Inch, 50 lbs Capacity - Aluminum Z Bar Clip Rail Bracket - Wall Mount Hangers with Nails - White Board Mounting, Shelf, Art by Luca Washington

Well done. High functionality. Depending on how heavy the object is, you can mount it to a stand behind the drywall, which means drilling a hole in the center (or just using one of the existing holes). Also, I added a thin layer of felt (fabric tape can be used) to avoid scratching the walls in the rental so it can be removed without seeing anything other than a small screw hole. Not necessarily if it is your own building. Exactly what I was looking for at a reasonable price.
