Starrett 51513 Steel Rule 72 in 16R Graduation Rigid

Product Description

The STARRETT 51513 is a rigid steel rule measuring 72 inches in overall length and 1-1/2 inches in overall width, designed for layout, fabrication, and inspection work in demanding trade environments. Built from spring steel with a satin chrome-plated finish, it delivers clear readability and corrosion resistance. The rule carries 16R graduation style with four scales: 1/32, 1/64, 1/100, and 1/50 inch, giving machinists, fabricators, and sheet metal workers the resolution they need across both fractional and decimal measurements. At 3.125 pounds, it holds its shape flat on a workbench or material surface without flexing.

This rule is suited for production shops, tool rooms, and fabrication floors where long, precise linear measurements are routine. The 72-inch length covers full-panel layout work in one pass. The horizontal scale orientation and satin chrome finish reduce glare under shop lighting, making graduation marks easy to read in both natural and artificial light. It installs flat without hooks or magnetic attachments, keeping setup simple.

Key Features

• 72-inch overall length covers full-panel and long-stock layout in a single pass
• 16R graduation with four scales: 1/32, 1/64, 1/100, and 1/50 inch
• Rigid spring steel construction resists bending under its own weight
• Satin chrome-plated finish reduces glare and resists surface corrosion
• Horizontal scale orientation for straightforward left-to-right reading
• No hook, no magnetic base — clean profile for direct material contact

Compatibility

Designed as a general-purpose rigid steel rule for machinists, fabricators, and sheet metal workers requiring long-length fractional and decimal layout capability.

Installation Notes

No installation is required for this measuring tool. Store flat to prevent warping and keep the rule clean of chips and cutting fluids that can obscure graduation markings. Inspect the rule periodically for nicks or burrs along the edges that could affect measurement accuracy. Handle with care near machining operations to avoid surface damage to the graduated face.
