Niigata seiki MD-2020 User manual

  • Hello! I've reviewed the instruction manual for the Niigata seiki's manhole depth measuring adapter, model MD-2020, and related satin steel square products. This manual details how to use the Hole-Man for precise measurements of step heights using a carpenter's square. The document also specifies the materials used, and provides measurement instructions for different cases. I'm ready to answer your questions about these features and their use.
  • What is the Hole-Man used for?
    What material is the Hole-Man made of?
    What is the maximum measurement for Case 1?
    How do I use the Hole-Man?
