This early 1900s set is solid brass. They have the swing bails to be used to open the drawers. The mounting posts, on the back side of the pulls, are located in the middle of the back plates. At the bottom of each back plate is a hole for a small brad or screw to secure the pull so it won’t turn or twirl in place. Each pull measures 2 1/2 inches wide and 1 3/8 inches vertically. Screws are included.
