High-precision digital folding ruler that combines four tools into one compact, job-ready instrument. Designed to speed up measurements, reduce errors, and replace multiple devices on the job. Key benefits Instant, easy-to-read measurements: Clear LCD displays precise angle readings so you can work faster and with greater confidence on carpentry, construction, and renovation tasks. Replace multiple tools: 4-in-1 design serves as a protractor, ruler, angle gauge, and bevel finder so you don’t need to switch tools mid-job. Built for durability and portability: 7-inch (230 mm) stainless steel folding ruler resists wear, folds flat for transport, and holds up to fieldwork and detailed indoor projects. Repeatable, comparative accuracy: Locking mechanism secures set angles for repetitive cuts and layouts; zero-reset function enables accurate comparative measurements on complex or uneven surfaces. Key features High-precision digital LCD: Instant numeric angle readout for faster setup and fewer mistakes. 4-in-1 multifunction tool: Measures angles, lengths, and bevels and functions as a protractor and ruler in one compact unit. 7-inch (230 mm) stainless steel ruler: Compact size for tight spaces; metal construction for long-term reliability. Lock and zero reset: Lock angles for repeatable cuts; zero function lets you take differential readings and transfer angles reliably. Practical applications Trim and molding installation: Quickly measure and lock compound angles for accurate miter and bevel cuts. Tile, flooring, and stair work: Transfer irregular angles and compare surfaces to get tight-fitting joints and consistent layouts. On-site carpentry and construction: Portable for field use—measure angles and lengths during framing, cabinet fitting, or HVAC/piping alignment without swapping tools. What makes it stand out Combines multiple measuring functions in one robust stainless steel tool, reducing clutter and setup time. Digital readout improves accuracy over eyeballing or manual protractors, especially on complex or repeat measurements. Compact folding design for easy carry and storage while maintaining professional-level durability.
