Features and Construction

This angle measuring tool combines functionality with straightforward design elements that support accurate measurement work across different surfaces and materials.
Material and Build
Constructed from ABS plastic, this carpentry ruler offers a balance of rigidity and lightness that makes it suitable for repeated use in workshop or home environments. The plastic composition resists moisture absorption and provides dimensional stability for consistent measurement accuracy over time. The material choice contributes to the tool's durability while maintaining a weight that facilitates easy carrying between job sites or storage locations.
Size and Practical Fit
With dimensions of approximately 30cm in length, 15cm in width, and 2.5cm in thickness, this measuring tool provides sufficient surface area for stable placement against workpieces while remaining compact enough for storage in toolboxes or drawers. The 30cm length offers adequate reach for measuring angles on medium-sized surfaces, from wooden desk corners to floor tile intersections, without requiring excessive repositioning during use.
Uses and Placement
The 180-degree scale and straightforward design make this tool applicable to various measurement scenarios in both professional and home settings.
Event or Professional Use
For carpentry professionals and serious DIY enthusiasts, this angle instrument serves as a reliable tool for verifying and transferring angles during furniture construction, trim installation, or architectural woodworking.
