UltraTest 12-Inch Steel Ruler with 5R Gradations - General Tools & Instruments

The General Tools & Instruments UltraTest CF1245 is a 12-inch steel ruler specifically engineered for the rigorous demands of professional automotive and industrial environments. This robust measuring tool provides precise, fine-resolution readings, making it an essential instrument for critical layout, inspection, and measurement tasks performed by automotive technicians, industrial machinists, and quality control personnel.

Key Features

• Precise 5R Graduations: Features 1/10, 1/100, 1/16, and 1/32 inch scales, offering exceptional versatility for both decimal and fractional measurements. This is ideal for tight-tolerance layout and verifying small component dimensions.
• Durable Stainless Steel Construction: Crafted from high-grade stainless steel, this ruler resists corrosion, warping, and edge damage when exposed to common shop fluids such as oils, coolants, and solvents.
• High-Contrast, Deeply Etched Markings: Permanent black gradations against a hard satin chrome finish ensure clear legibility in various lighting conditions and maintain clarity after repeated cleaning.
• Optimal 12-Inch (300 mm) Length: Provides ample reach for common under-hood, chassis, and fabrication measurements on passenger cars, light trucks, and fleet vehicles without being cumbersome.
• UltraTest Accuracy Standard: Manufactured to meet or exceed U.S. Government Specification GGG-R-791f, guaranteeing consistent, reliable readings essential for professional automotive, machining, and fabrication applications.

Applications

Designed for daily professional use, the CF1245 excels in critical tasks such as alignment, suspension work, exhaust system adjustments, and bracket fabrication. Technicians and machinists can utilize it for accurately marking tabs and mounting points, plotting precise hole locations, and verifying cut lengths. It is also suitable for checking clearances, measuring gasket and shim thickness, and performing quick quality control checks on small components across welding benches, machining cells, and various maintenance departments.
