1. UPDATED ANGLE MEASURING RULER Our multi angle measuring ruler is newly upgraded with rich features. It serves as both a measuring tool and a tile positioning hole opener. Unlike common measuring rulers that only include a four piece set, our newly upgraded universal square features a six piece ruler. Simply adjust the six metal buttons to create the desired shape, making it quick and easy to measure objects of various shapes. 2. PRECISE ANGLE MEASURING TOOL This angle tool features laser engraved markings (inches and centimeters), making it ideal for precise angle measurements. You can adjust the size to mark tiles accurately. The metal protractor is a tool for measuring and integrated hole positioning. 3. QUALITY ALUMINUM ALLOY This multi angle measuring ruler is crafted from aluminum alloy, ensuring it won't break from bending or rust. It's more durable and stronger than plastic alternatives. 4. TIME SAVING Use the sliding ruler to quickly measure angles and sizes, lock it in place, then attach the ruler to the material you need to cut. This allows for fast marking and cutting, saving you time and boosting your work efficiency and productivity.
