Draw circles, measure angles on a whiteboard or for DIY on plastic or laminate surfaces to assist cutting round holes.
Smallest circles = 6 cm, largest circles = 30 cm with increments of 2 cm.
Operates with pilot whiteboard marker and Berol dry wipe by inserting through the holes or any other marker by holding against the serrated edge.
The attached protractor allows angle measurement.
The unit is attached via a powerful sucker at the pivot point.
The long arm is made of 3 mm steel so would be extremely difficult to bend or distort.
How to use
- Attach via the sucker at the point that is to become the centre of your circle/s
- Insert a marker (of the type listed above) through a hole (it will stay in place).
- Rotate to draw a perfect circle.
- If using another make of marker then it must be held in a serration (slightly more difficult as it will not be held captive.
- The protractor can easily be removed if not required.
It has many uses in education and diy for marking holes in many materials provided the sucker will hold.
Please note no pens are included.
