This Victorian Era(Late 1800s) pull has a cast brass backplate with steel posts and bail. The holes are 3″ apart. The overall dimensions of the back plate is 4″ wide by 1 3/4″ high. Originally the posts were crimped onto the backplate, but some of the posts have come loose over time. This, however, does not affect the functionality of the pull. Once installed, the posts will stay firmly in place.
