 Parallel flat foot with the exact plane foot-shaped gauge. Square foot for coloring, indicating the plane of the table method, inspection plate, long rails, etc., but also commonly used in the straightness of the edge of the optical gap law of the workpiece edge. Square foot general manufacturing, high-quality cast iron rectangular square foot is also useful for manufacturing of bearing steel or granite. 
 Parallel to the flat-foot: Press JB/T7977-99 standard manufacturing, material HT250, working surface scraped or precision grinding process used to machine inspection and test roughness and straightness of the two face is in line with the block gauge, micrometer, level meter and other equipment inspection, different heights, the parallel between the two rails and the rail level, and not connected with the rectangular device, the test using only a rectangular device can not test the two parts of the vertical measuring, but also applies to equipment installation and inspection.
