The granite parallel is mainly applicable for inspecting the perpendicularity and depth of parallelism. It is characterized by uniform texture, good stability, as well as high strength and hardness. Even under the condition of heavy loading, it still can guarantee the high accuracy. Our precision granite parallel is suitable for the measurement in the industrial production and laboratory.
Our granite parallel rulers are supplied in pairs, and should be used in pairs.Parameters
