This is an outstanding old brass pull pair. The ring actually hangs from a bar that swings from a heavy round post/bolt. The pull is backed by a convex round back plate. This pair dates to the late 19th Century or early 20th Century.
The stamped brass back plate is 1 3/4 inches round. The only decoration is the rick-rack type edging. The ring measures 1 7/8 inches across and 1 1/2 inches deep. The bar from which it hangs is 2 inches long. The 1/2-inch wide brass post is the head for a 1/4-inch bolt. The bolt extends 3/4 inch past the back plate. The pull is secured with a nut on the back of the drawer.
Nuts are included.
