Westcott B-97 24" English/Metric Transparent Ruler

The Westcott B-97 is a 24-inch transparent ruler designed to handle everyday measuring, drafting, and layout tasks with accuracy and convenience. Its dual-scale design features 16ths-of-an-inch calibrations with an 8ths graph feature on one side and millimeter markings on the other, with each centimeter line extended to the inch scale so users can quickly compare English and metric measurements without switching tools. The zero-centering English scale is a thoughtful addition for anyone who frequently needs to find the midpoint of a line or distribute spacing evenly from a center mark.

Constructed from transparent plastic, the ruler allows full visibility of the work surface beneath it, making alignment over drawings, blueprints, or printed layouts straightforward. The laminated finish protects the printed graduations from rubbing off and adds a degree of scratch resistance that extends the ruler's useful life. At 24 inches, it provides ample length for larger-format work while remaining a standard size for most drafting tables and workstations.
