Most ice box hinges are brass. Then, some of the brass hardware was plated with nickel. This set of six is nickel-plated brass, but quite a bit of the nickel has rubbed off. These can be left as is when applying them to the ice box for an old look, or you can scrub the nickel plating off and have a set of brass hinges. These are off set by 3/8 inches. The door leaf is 1 7/8″ x 1 5/8″ wide. The frame side leaf is 1 1/4″ x 1 5/8″ wide. The hinges are loose and ready to install. Screws are included.
