How: ▶Wide measuring range2 plastic feet to measure and transmit wall angles from 30 to 180°, and then align the angle on the miter saw. ▶Make cuts accurate offers, 2 magnets attach directly to the saw blade to replicate the angle to be cut, making the miter saw more precise. Practical and convenientIncludes ▶telescopic angle clamps for external corners and integrated folding stops for easy marking on workpieces workpieces, both inside and outside, corners can be measured, and angles can be easily marked on the workpiece. ▶Special eccentric rod designThe special lever design makes it easy to operate, even in tight working areas, the data can be measured and perfectly transmitted to the miter saw.
