Product Description

This Ring Ruler is the first size-adjustable, circular ruler.It has been designed to make the drawing and measuring of circles and arcs amuch simpler, more efficient experience by eliminating the cumbersomepivot-point system.

Rule is 19″ long; maximum diameter is 6″.One of the best features of the Ring Ruler is its simplicity. This makes it agreat learning tool for children – especially ones too young to handle a circlecompass.
