For sale is a Niagara No.4 Bar Folder, Serial No.30569. Manufactured in the USA circa 1930's - 40's. 36" Overall length of bending platen. Here are some thoughts on a very similar Niagara: "this Niagara bar folder is an interesting combination of ingenious mechanisms to make narrow (less than 2" wide flange) sheet metal bends. The only difference between a bar folder and a sheet metal brake is the narrow depth capacity, a focus on making accurate sized flanges, and an ability to bend considerably beyond 90 degrees in order to make seams for interlocking sheets together, such as in air conditioning ductwork. It resembles the small brakes sold by J.C. Whitney and Harbor Freight, but the resemblance is only superficial. The size of the pivot bearings is close to the size of those on an engine crankshaft!" Please review the photographs, and do not hesitate to ask me any relevant questions about this item. NOTE: What you see in the pictures is what you will receive. There are no additional parts or accessories that come with this bar folder.
