The ring pulls on this pair are hinged at the top of the back plates, and the mounting posts are in the center of the pulls. The back plates, however, is slightly smaller than the pull rings, which is different. On most of these pulls, the ring nestles into the back plate. The cast brass plate is 1 3/8 inches round, while the over-laying ring is 1 5/8 inches round. The pair is also typical for this style: there is a center flower or button and the ring is decorated. There is a small hole at the base of the back plate in order to secure the pull with a small brad or screw. This prevents the back plate from twirling in place. Mounting screws are included.
