Precision dualscale ruler with builtin 90degree guide — designed for plate making and handcraft plates. Clear markings, durable thickness, and two length options make measuring, marking, and cutting faster and more reliable. Key benefits Accurate measurements: Graduations on the ruler body are clearly numbered for easy reading and reliable results. Dual units: Outer edge in inches, inner edge in metric with cm and mm markings for versatile use. Two size options: Available in 8 in and 16 in lengths to match small and larger projects. Builtin 90degree guide: The integrated 90degree protractor makes rightangle layout and alignment simple without a separate tool. Comfortable and durable: Thick construction reduces sharpness of edges and resists bending, making the ruler safer and longer lasting during repeated use. Multipurpose: Useful for plate making and handcraft plates while remaining suitable for general measuring, marking, and cutting tasks. Features and function Clear, numbered graduations on both inch and metric scales for quick visual checks and precise placement. 8 in or 16 in outer inch scale with internal cm and mm scale for compatibility with imperial and metric workflows. Integrated 90degree guide enables fast square checks and consistent corner alignment. Robust thickness minimizes hand discomfort and improves stability when drawing or cutting. Practical use scenarios Plate making: Mark and measure plate layouts, transfer precise dimensions, and use the 90degree guide to ensure square cuts and accurate holes. Handcraft plates and hobby projects: Measure, score, and cut materials with clear graduations and a stable edge to improve repeatability and finish. General workshop and studio tasks: Use for layout, rightangle checks, trimming and aligning templates where both inch and metric measurements are needed. Specifications Scales: Outer inch scale (available in 8 in and 16 in), inner metric scale in cm and mm Markings: Numbered graduations, clear and accurate Function: Measuring, marking, rightangle layout (90degree guide), cutting guide Construction: Thick profile for durability and safer handling What you get A practical, reliable ruler built for plate making and handcraft plate work, offering dualunit precision, a builtin 90degree guide, two size choices, and clear numeric graduations for everyday accuracy.
