Try squares are essential measuring tools used in woodworking, metalworking, and other trades to ensure accurate right angles and straight lines. They consist of a metal or wooden handle with a blade or stock that forms a 90-degree angle. Try squares work by aligning the stock against the edge of a workpiece and checking if the blade is perpendicular to it. This allows craftsmen to verify the squareness of corners or check if an edge is straight. Woodworkers, carpenters, metalworkers, and DIY enthusiasts are among the chief beneficiaries of try squares. Equipped with an accurate ruler that has both metric and imperial units marked on both sides, Ronix RH-9730 is one of the larger members of our lineup of try squares. Just like its brothers, it is made of hardened aluminum and is ready to be your companion for years to come.
