This bin pull probably came off of a large drawer on a hardware store or lumber-yard cabinet. It was made to handle a great deal of weight or pull. Because of the pattern, we know that this pull dates from the late 1800s to the early 1900s.
The pull measures 4 1/4 inches across with hole centers at 3 3/4 inches. Its vertical measurement is 3/4 inch. The pull projects from the surface 3/4 inch, which allows room for four fingers.
Screws will be provided.
To keep old cast iron looking good, apply with a rag a bit of furniture oil.
