Multi-Angle Measuring Ruler - Removable design: The multi-angle ruler is detachable. When you tighten the screw, it becomes a 3D measuring tool for complex layouts. If you don’t need it, use a hex key to remove the screws and obtain a square ruler and a miter triangle ruler. - Laser-engraved metric scale: The carpenter ruler is laser-cut with a clear, accurate metric scale for easy, precise readings. - Premium construction: Made from high-quality aluminum alloy. Rust-proof, high hardness, good toughness, and lightweight for comfortable handling and long-lasting use. - Versatile functionality: The ruler supports measuring, correcting, and marking and can cover measurements across multiple feet, improving woodworking efficiency and saving time. - Practical applications: - Create precise miter joints and frames by converting to a 3D measuring tool as needed. - Layout and align cabinet frames, shelves, and doors using the square and miter configurations. - Quick multi-board checks on long pieces to ensure consistent marks and angles along the run.
