This Eastlake pull that dates over 100 years old is all cast brass, including the posts and swing bail. The decorated bail is original to the back plate.
The back plate measures 4 inches horizontally and 1 1/2 inches vertically. The total drop including the bail is 1 3/4 inches. The hole centers are 3 inches apart. The heavy posts extend beyond the back of the plate 1/2 inch. Screws are then fed from the back of the drawer and threaded into the posts. Screws are provided.
