Regla de escala Staedtler 562 300 PB 300 mm Transparente

The Staedtler 562 300 PB 300 mm Transparent scale ruler is a clear plastic measuring tool designed for accurate linear measurement in drawing and technical work. Its 300 mm length and transparent body allow precise alignment over drawings and printed plans. Markings are printed for readability and accuracy, while the lightweight construction supports comfortable, extended use. The product is supplied in blister packaging to protect the ruler during storage and transport.

Advantages

The transparent construction provides unobstructed visibility of the drawing surface and underlying gridlines, helping to improve alignment and measurement accuracy. Fine, evenly spaced markings ensure precise readings across the full 300 mm length. The durable plastic material resists breaking under normal use and remains dimensionally stable for consistent results. Its slim profile and low weight make it easy to carry in a pencil case or bag.

Suitable for

• Technical drawing and drafting
• Architectural sketches and plan reading
• School geometry and student work
• Graphic design and layout alignment
• Everyday measuring tasks in offices and workshops

Key specifications

• Length: 300 mm
• Material: transparent plastic
• Scale type: linear metric graduations
• Marking visibility: high-contrast printed graduations
• Profile: flat, slim edge for drawing accuracy
• Packaging: protective blister

How to use

Place the transparent ruler directly on the drawing or surface to be measured, aligning the zero mark with the starting point. Read the measurement at the endpoint using the printed graduations, ensuring your eye is directly above the mark to avoid parallax error. Use the slim edge of the ruler as a guide when drawing straight lines with a pencil, pen or technical pen. For repetitive measurements or layout transfer, hold the ruler steadily with light pressure to maintain position.

Recommendations

Store the ruler flat or in a protective case to prevent bending. Clean with a soft cloth and mild detergent if necessary; avoid abrasive cleaners or solvents that could degrade the printed markings. For precise technical work, check alignment visually and avoid using a ruler on heavily textured surfaces that may affect reading accuracy.
