These are antique iron barn or shed door rollers and hangers. These show wear and oxidation with rust and some bending.  They could probably be made useable but need some hammer work.  This pair of salvaged sliding door hangers would add a touch of vintage decor to any space. The rusty patina and original design make them a unique display item.     Use them to hang a barn door or as an eye-catching display piece. They are 6" in width and 10-1/2" in length.  Maker is unknown maker. These antique iron barn shed door rollers and hangers are a must-have for any antique or architectural enthusiast.
