Westcott ZC-24 24-inch Zero Center Stainless Steel Ruler

The Westcott ZC-24 is a 24-inch stainless steel ruler built for professionals, students, and hobbyists who need precise, repeatable measurements in drafting, design, and layout work. Its defining feature is the zero-center scale, which places the 0 mark at the ruler's midpoint with measurements extending outward in both directions. This design eliminates the arithmetic normally required to find a center point or create symmetrical layouts—you simply align the zero and read off equal distances on either side. The ruler's etched markings include 1/16-inch imperial graduations and metric increments, providing dual-system versatility on a single tool.

Constructed from warp-resistant stainless steel with a chrome finish, the ZC-24 maintains straightness and accuracy over extended use. The flexible steel can conform to gently curved surfaces for measuring or marking without losing legibility, a useful capability for tasks beyond flat-surface drafting. A non-slip cork backing on the underside grips paper, drafting boards, and tabletops to prevent the ruler from shifting mid-measurement, resulting in cleaner lines and more consistent results. At just 3.2 ounces, the ruler is easy to handle for extended periods, and a built-in hang-hole allows wall-mounted storage to keep desk space clear between uses.
