Centrum 50 cm plastic ruler CE81828 is a straight measuring tool designed for everyday use in school, office and studio environments. Made from durable transparent plastic, the ruler provides clear printed markings across the full 50 cm length for accurate linear measurement. Its slim profile and lightweight construction make it easy to handle, store and carry in pencil cases or desk drawers.

Advantages

The transparent plastic construction offers good visibility of the drawing surface beneath the ruler, while the full-length printed scale ensures consistent measurement across the entire 50 cm span. The slim, lightweight design reduces bulk in carrying cases and allows precise placement for drawing straight lines. The ruler resists minor bending and is easy to clean, supporting long-term classroom or office use.

How to use

Place the ruler on the surface to be measured or marked, aligning the zero point with the starting position. Hold the ruler firmly to prevent slipping, then read the required measurement from the printed scale or draw along the edge with a pencil or pen. For longer straight lines, keep consistent pressure and reposition the hand as needed to maintain alignment. After use, store the ruler flat or in a pencil case to avoid unnecessary bending.

Usage recommendations

For accurate results, use on a flat, stable surface and clean the edge regularly to remove residue that can affect marking precision. Avoid exposure to high temperatures to prevent warping of the plastic. When transporting, place the ruler in a protective sleeve or pencil case to maintain straightness and printed scale clarity.
