A ruler with 4 holes is a precision-designed measuring tool made from high-quality transparent Perspex sheet or durable plastic moulded material, ensuring long-lasting performance and reliability. Measuring 265mm in length, 20mm in width, and 3mm in thickness, this ruler is crafted to provide both accuracy and convenience in a wide range of educational, professional, and technical applications. Its transparent body enhances visibility of the underlying surface, allowing users to achieve exact measurements without obstruction, making it especially useful in drafting, design, and classroom activities. The sleek and sturdy construction ensures that the ruler remains resistant to bending, cracking, or warping, even with frequent use, offering a dependable option for students, teachers, engineers, and designers alike.
Description
The unique feature of this ruler is its four carefully positioned slots, each measuring 25mm x 5mm with ends rounded into a semi-circle for smoothness and safety. These slots are precisely located to support a variety of practical applications: the first slot is positioned from 0–25mm, the second slot from 70–95mm, the third from 140–165mm, and the fourth from 210–235mm. This precise alignment allows for enhanced functionality, such as drawing parallel lines, marking intervals, or facilitating technical work that requires accurate spacing. The rounded slot ends ensure safe handling, preventing sharp edges while offering easy movement of pencils or markers during use. The innovative design makes this ruler far more versatile than conventional ones, adding value in both academic and professional environments.
The ruler is marked with bold black colour measurements, ensuring excellent visibility and readability against the transparent background. This feature enhances usability in different lighting conditions, reducing the chances of error and improving measurement accuracy. The black markings are resistant to fading, ensuring that the ruler maintains clarity and effectiveness over time, even with heavy usage. Whether used for simple schoolwork, professional drafting, or intricate design tasks, the precision of its markings ensures consistent results. Its measurement scale is perfectly aligned, providing accuracy for both straight-line measurements and alignment tasks.
This ruler with 4 slots proves highly useful in educational institutions, where it is often employed in physics, mathematics, and technical drawing classes to demonstrate concepts of measurement, spacing, and geometry. It is also widely used by architects, engineers, and designers who require a practical and reliable measuring tool for sketches, blueprints, and layouts. The inclusion of multiple slots makes it particularly useful in workshops or laboratories, where exact placement and alignment are critical.
Durability is another key strength of this ruler, as it is manufactured from premium Perspex or moulded plastic that ensures resilience against wear and tear. Its lightweight yet sturdy build makes it easy to carry and convenient to use, while its slim design allows it to fit easily into stationery cases, toolkits, or laboratory drawers. The smooth finish prevents scratches on paper or surfaces, ensuring neat and precise work every time. The combination of functionality, durability, and ergonomic design makes this ruler not only an essential academic tool but also a valuable resource for technical and creative professionals.
In summary, the transparent ruler with 4 holes is a high-quality, precision-made measuring tool designed to meet the diverse needs of students, teachers, engineers, and designers. With dimensions of 265mm x 20mm x 3mm, bold black markings, and four strategically placed slots, it offers unmatched versatility and accuracy.
