Klein Tools 911-6 Folding Ruler 6-Foot | Durable Fiberglass Outside Reading

Overview

The Klein Tools 911-6 Folding Ruler is a 6-foot fiberglass-reinforced measuring tool designed for professional use on busy worksites. Its outside-reading style lets you take quick measurements from the edge, while the bright yellow blade with black markings stays visible in cluttered spaces.

Durable by design

This rule uses tough nylon reinforced with glass fibers, delivering a blend of stiffness and flexibility that can handle weather, abrasion, and many chemicals. Positive locking joints and stainless steel spring hinges add strength for repeated folding and unfolding, so you can rely on it project after project.

Readability and accuracy

Measurements are marked on both sides and on both edges, graduated to 1/16 inch (1.6 mm). Engraved graduations remain legible over time, with black markings on a high-contrast yellow blade and red center markings every 16 inches to support fast, confident reference.

The outside-reading layout helps when you’re measuring from the edge of a workpiece, so you can view the scale exactly where you need it most.
