- Multifunctional foldable Libellineal: This ruler is designed with multiple functions and can be folded for storage and transport. It is a tool for improvements and projects. - High precision and magnetic balance ruler: Built-in strong magnet strip allows attachment to metal surfaces and helps ensure accurate measurements. - Multi-angle measuring tool: The hinge design lets you set the ruler to different angles, including 180 degrees, 90 degrees, and 45 degrees, making it suitable for measuring and line drawing tasks. - Integrated bubble levels: Four bubble levels are built in, including a 180-degree level for measurement and line drawing, a 90-degree level for measurement and line drawing, and a 45-degree level for 45-degree measurement and line drawing. These bubbles provide visual orientation for straight measurements. Use cases - Woodworking and DIY projects: use for quick layout, aligning edges, and marking 90 and 45 degree lines; magnet helps keep it steady on metal work surfaces. - Home improvement and tiling: transfer angles and draw straight lines on walls or panels; use the 90 and 45 degree references for accurate cuts. - Metal fabrication and general construction: hold the ruler in place on metal parts with the magnet, measure long edges, and verify angles with the built-in levels.
