KERN Reisszeug 5-fach Zirkel C 403 S, Silver, 150 mm

KERN Reisszeug 5-fach Zirkel C 403 S – Precision Compass for Technical Drawing

The KERN C 403 S is a 5-fold scaling compass designed for accurate proportional divisions in technical and architectural drawing. It enables users to reproduce or reduce scale drawings with precision, making it an essential tool for draftsmen and engineers.

• 5-fold scaling mechanism allows proportional enlargement and reduction of drawings
• Silver finish provides a durable, corrosion-resistant surface for long-term use
• Maximum circle diameter of approximately 400 mm (15.7 in) accommodates large-format work
• Compact total length of 150 mm ensures comfortable handling and storage
• Weighs only 127 g — lightweight enough for extended drafting sessions without hand fatigue

Das zeichnet den KERN C 403 S aus

Unlike standard single-division compasses, the 5-fold mechanism of the KERN C 403 S lets users set a precise ratio between the input and output points in a single adjustment. The silver-plated body resists tarnish and the hardened steel points maintain sharpness through repeated use on drawing paper and film.

Ideal für...

Technical drafters, architects, and engineering students who require proportional scaling directly on their drawing surface. The compact 150 mm length fits comfortably in a drafting toolkit or pencil case alongside scales and rulers.

Anwendung von KERN Reisszeug 5-fach Zirkel C 403 S

1. Set the desired scaling ratio using the 5-fold adjustment mechanism
2. Secure the compass point on the reference point of the original drawing
3. Trace the scaled circle or arc onto the target drawing surface
4. Verify the proportion against the original before finalising the line
