ANTIQUE CAST IRON CHIMNEY CLEANOUT DUTCH OVEN DOOR B. This is a smaller size antique cast iron clean out door or Dutch oven with door frame. It measures 10 1/8″ wide x 12 5/8/” high x 3 deep including handle. The inside measurement for the opening required would be a mimium of 7 1/2″ wide x 9 5/8″ high. Great condition It was completely cleaned and finished in a high heat black that gives it an Original patinaed look. Inside round damper may be a replacement done sometime ago to keep this item working, if so it was well done. What a great looking Handle and Nice design.
