High-quality plastic marking gauge for marking (outdoors) on all kinds of work pieces. It can be used with any commercially available folding ruler of 1 m and 2 m and can be locked with a rotating screw.

The closed case for the pen is placed at the end of the folding ruler and is used for:

• Safe driving of the pens
• Assistance for parallel lines and circles

A central point provides a more secure grip when drawing circles.
