Try squares are essential tools used in carpentry, woodworking, and other precision-based tasks and consist of a metal blade and a handle at a 90-degree angle to the blade. Their main goal is to provide a reliable and accurate way to check and mark right angles. The blade is aligned with the edge of the workpiece, ensuring a perpendicular angle. Carpenters, woodworkers, and DIY enthusiasts benefit from using try squares as they enable precise measurements and ensure the accuracy of cuts, joints, and assemblies. Ronix RH-9720 is a 20cm try square made of hardened aluminum material with a ruler accuracy of 1mm per meter which makes it the perfect option for general carpentry, metalworking, and measuring as well.
