About this item

• Size - Measuring range: 31cm / 12"; system: SAE; Minimum scale: 1/16"; Thickness: 3mm / 0.12"; Folding length: 16cm / 6.3"; Package include: 1 x folding straight ruler
• Material - The office ruler is made of aluminum alloy, which makes it hard and durable, not easy to deform or damage, ensuring measurement accuracy; Lightweight aluminum alloy ruler is more flexible to operate and convenient for one-handed operation or long-term continuous measurement. Anodized surface can effectively prevent the aluminum alloy surface from corrosion or rusting, extending the service life of the folding ruler.
• Feature - The geometric ruler adopts a center rotation design, which is more stable when rotating, ensuring the accuracy of measuring and drawing angles. The angle scale is clear, and the angle value can be read intuitively to avoid reading errors and improve work efficiency. The folding design takes up little space and is easy to carry and store.
• Application - Folding straight ruler is widely used in geometric drawing, plane drawing, composition planning, and mathematical chart drawing. Suitable for classrooms, architectural design, art design office occasions, and other work environments that require precise measurement or drawing.
• Note - Try to avoid collision of the folding ruler with hard objects to prevent damage to the scale and affect the measurement accuracy. Please do not bend the folding ruler to maintain its accuracy and stability.
