This thing helps hang more than just frames... it helps with shelves too. Does your shelf have an L-Brackets that hold it up? If so, that is a bracket shelf and, yup, the Hang It Perfect can do it! Does your shelf have those keyhole mounts on the back side, which are those little holes with those slot thingies that you put the head of the nail into, slide down to lock into place and are super-duper annoying to hang? Those are floating shelves, and well, you guessed it, the Hang It Perfect is perfect for those!
