Product Information:

The Ring Ruler™ is the first size-adjustable, circular ruler. It has been designed to make the drawing and measuring of circles and arcs a much simpler, more efficient experience by eliminating the cumbersome pivot-point system. Not only is the natural feel of expanding and contracting a circular ruler more ergonomic than using a needle compass, it is also quicker, safer and provides the more useful circular metrics of diameter and circumference (arc length). Rule is 19" long; maximum diameter is 6".

One of the best features of the Ring Ruler™ is its simplicity. This makes it a great learning tool for children – especially ones too young to handle a circle compass.

Comments about Koala Tools Ring Ruler - Standard :

I was pleasantly surprised at how easily and quickly I got the hang of using this little circle ruler. I needed it for a particular purpose of semi-large rounding of some boards. I can see some different uses and will keep on my pegboard for future use.
