JessEm Stainless Steel Precision Rules

Precision Measuring You Can Rely On

The JessEm Stainless Steel Precision Rules add grip, durability, and clarity to your measuring tools. Crafted from hardened 301 stainless steel and finished with laser-etched plus engraved markings, these rulers provide long-lasting accuracy that won’t fade. 

Grip That Prevents Slipping

Each ruler includes patented Flex Tabs that grip to virtually any surface softer than the steel itself—wood, metal, paper, etc.—to prevent sliding while scribing, marking, or measuring. 

Size & Scale Options

Available in both Imperial and Metric with a variety of lengths to fit your projects:

• Imperial: 6", 12", 18", 24" 
• Metric: 150 mm, 300 mm, 450 mm, 600 mm 

Features & Benefits

• Long-lasting markings: Laser etching plus engraving ensures the graduations never fade. 
• Durable construction: Hardened 301 stainless steel resists wear and warping in the shop environment. 
• Dual-marked scales: Graduations are on both sides of the rule, with common incremental spacing (1/16", 1/32", etc., for Imperial; fine divisions for Metric) 
• Anti-slip Flex Grip: Flex Tabs lock the ruler in place to reduce measurement errors caused by shifting.
• Wide usability: Perfect for woodworking, metalworking, drafting, art, design, and other precision applications.
