Clear and precise measurements: The 230-mm ruler features clear, bright bubble vials for accurate and reliable readings. It delivers precise results without contamination or inconsistencies, ensuring accuracy every time. Angle gauge and levels: Equipped with a 45-degree reference and vertical and horizontal level indicators, it provides three measurement modes: length, angle at 45 degrees, and vertical/horizontal level checks. The user friendly design makes it easy to use and helps you work efficiently. Secure magnetic base: A magnetic underside lets you attach the ruler securely to metal surfaces, enabling hands-free use and improved stability during measurements. The magnet keeps the tool within reach to boost productivity. Robust and reliable: Made from durable materials, it is drop-resistant and impact-resistant, built to withstand demanding work environments. It offers long-lasting performance and durability under heavy use. Use scenarios: - Woodworking and carpentry: align components, lay out angles, and install shelves with hands-free stability. - Metal fabrication and installation: verify 45-degree angles and ensure level faces during assemblies. - DIY home projects: cabinet installation, tile layout, and precise marking with reliable measurements.
