This ruler is built to be used in conjunction with other products by Circle Perfect Tools, such as the CPT Degree Scales and the Circle Guide for Router Table. Although it can function by itself as a ruler, it has some extra capabilities when used with the CPT Degree Scales because of the specially designed center pin holes in both tools, allowing operator to quickly rotate and draw straight lines at measured angles.
