Non-slip design: A strong suction cup base provides stable, non-slip grip during measurements and prevents tipping or sliding on metal-like surfaces. Ease of use: Magnetic leveling pins emphasize simple operation and precise results. Quick setup lets you obtain accurate measurements with clear readings. Portability: Folding structure allows fast opening, easy storage, and convenient transport, maximizing space efficiency in the workshop or on site. Multiple functions: Combines vertical measurement with a protractor for versatile solutions across many scenarios. Designed to improve efficiency with practical features. Use scenarios: - Align shelves, brackets, or frames on metal surfaces such as workbenches, racks, or machinery to ensure true vertical alignment. - Check plumb and level during installation of metal structures, rails, or equipment in fabrication or assembly lines. - Verify angle and inclination for miter joints or mounting brackets on metal furniture or equipment. Materials and performance: Magnetic spirit level with a suction cup base for stable fastening, combining vertical measurement and protractor capabilities to deliver reliable, fast readings in diverse environments.
