Premium Pacific Arc EE-Series 18" Ruler. Precision you can count on, project after project. This high-quality stainless steel architect ruler is tougher than aluminum, so it won’t bend, warp, or wear out. Etched markings on both sides and finely detailed imperial graduations (down to 32nds and 64ths) make it perfect for accurate drafting and design work. With a non-skid cork or rubber backing, it stays put while you focus on the details—ideal for tech students, artists, and future architects alike.
