Compass Linex 401 metal with adjustable legs for precision drawing

Metal compass Linex 401 with adjustable legs for precision drawing is a workshop and classroom tool designed to produce accurate circles and arcs. Its sturdy metal construction ensures dimensional stability while the adjustable legs permit a wide range of radii and fine positioning. Designed for technical drawing, drafting, geometry lessons and hobby projects, the compass provides repeatable results for both professional and student use.

Advantages

The compass combines a robust metal frame with precise adjustment mechanics to minimize wobble and maintain consistent radius settings. Adjustable legs allow incremental changes to circle size and the instrument accepts standard leads or a scribing point for different materials. The compact design makes it easy to store in a drawing case or pencil box, and the metal build offers long-term durability under normal use.

Suitable for

• Technical drawing and CAD preparatory work
• Architectural and engineering sketches
• Geometry lessons and classroom exercises
• Hobby crafting, model making and pattern layout
• Precision marking on paper, cardboard and thin sheet materials

Key specifications

• Material: metal frame and legs for stability
• Leg adjustment: fine adjustment mechanism for precise radius control
• Point type: accepts standard pencil leads; removable scribing point compatible with thin materials
• Maximum and minimum radius range: suitable for small to medium circles used in technical and educational tasks
• Weight and size: compact, portable design for easy storage and transport

How to use

Place the fixed point on the intended center of the circle and set the other leg to the desired radius using the adjustment mechanism. Tighten any locking screw or clamp to secure the selected radius before drawing. Insert a sharpened pencil lead or attach the scribing point as required by the material. Hold the compass vertically and rotate the moving leg smoothly around the fixed point to draw an accurate circle or arc. For repeatable results, mark the radius setting on the instrument or transfer the measurement with a ruler.

Usage recommendations

Use a well-sharpened pencil lead for clean lines on paper; switch to the scribing point for marking thin metal or plastic. Keep the adjustment mechanism clean and occasional light lubrication on the pivot will preserve smooth movement. Store the compass in a protective case to prevent bending of the legs or damage to the points.
