Featuring both inch and centimeter markings, this 20-inch (50cm) ruler delivers accurate measurements for drafting, technical drawings, and everyday use. The heavy-duty stainless steel construction ensures long-lasting performance and maintains straightness even with regular use. Adding convenience and protection, it comes with a leather cover that keeps your ruler secure when not in use. The substantial build quality and practical length make it ideal for architects, engineers, students, and craftspeople who need reliable measurements for their projects. The clear, easy-to-read markings on both scales help prevent measuring errors, while the sturdy steel material resists wear and tear from daily use.
