Marble Right Angle Square is suitable for detecting verticality. Plane accuracy standard GB6092-85, verticality standard GB6092-85. Weight reduction holes have been added to reduce weight and facilitate processing. The tolerance on the side is 0.02.

Marble Right Angle Square is a measuring tool used for marking, equipment inspection, measurement, installation, and industrial engineering construction. It is abbreviated as an angle ruler and is sometimes referred to as a guiding rule. It is used to detect the verticality of workpieces and their relative positions, and is also used for marking.

Marble Right Angle Square is suitable for verticality inspection, installation, processing positioning, marking, etc. of machine tools, mechanical equipment and components. It is one of the measuring tools in the mechanical industry, with good stability, high accuracy, and easy maintenance.

The main mineral components of a Marble Right Angle Square are plagioclase, pyroxene, a small amount of biotite, olivine, and trace amounts of magnetite. After billions of years of aging, it has good stability, uniform texture, high hardness, and strong strength, and can maintain high precision under heavy loads. Suitable for laboratory measurement and industrial production.
