Abstract: A tool for marking sheet metal prior to bending in a bending brake, includes a scale having a first end, an opposite second end, a longitudinal axis, and four faces. Each of the four faces include a plurality of marking stations. A cross member is rotatably connected to the first end of the scale. The cross member has a surface which is disposed perpendicular to the longitudinal axis, and is configured to abut the edge of the sheet of metal. The tool is positioned at a first location on the sheet of metal and marks are made at the marking stations. The tool is then moved to a second location on the sheet of metal and a second set of marks are made. The two sets of marks are used to align the sheet of metal with the bend line of a bending brake so that accurate bends can be made.
