A house bell on a carriage that is connected with wire which I will supply once you determine how long you need. The bell measures 6 x 13 inches long which I was told was old store stock all other parts have never been installed. The brown mineral door bell pull is 2 inches in diameter and usually mounts on the outside door jamb or the wall. The 2 triangular pieces are when you need to make a 90 degree with the wire.
Please take a look at my other hardware in my store, thank you.
