This Wiha folding ruler is seriously tough stuff! Made from composite construction with glass fiber layers, it's more rigid than wooden rulers and won't swell or warp with water contact. The 2-meter length with 10 folding arms makes it super versatile for all kinds of measuring jobs. The joints are play-free and dirt-resistant with spring pins that keep constant tension - they latch securely at both 90° and 180° positions. Features unlockable metal ends at both tips for accurate measurements from edges. The red/black version has a deep-embossed white scale in 1mm increments that's easy to read. Meets EU standard accuracy class II and CE conformity, so you know you're getting precise measurements every time. The reverse routing scale lets you take readings from either direction. Perfect for woodworking, construction, DIY projects, or any situation where you need a reliable, durable measuring tool that can handle job site conditions. If you're tired of flimsy tape measures or rulers that don't hold up, this German-engineered folding ruler is built to last.
