C-Thru Proportional Scales

Calculates enlargements and reductions of just about anything from photos to quilts. Provides the number of times reduction as well as the percentage of enlargement or reduction. On the PS-69, PS-79, and PS-80 calibrations for fractions below an inch are printed in a second color.

Note: The C-Thru ruler company was recently acquired by Wescott and as such the products your receive may be labeled with either the Wescott or C-Thru brand name while this transition of ownership is completed.
