Premium Stainless Steel Drafting Ruler. Measure twice, draft once—with confidence. This premium stainless steel ruler is built for precision and durability, with etched markings on both sides and fine graduations down to 32nds and 64ths of an inch. Stronger than aluminum and resistant to bending, it stays accurate under pressure. The non-skid cork (or rubber) backing keeps your lines sharp and your ruler steady—perfect for tech drawings, set design, and serious sketching.
