PRECISE: The contour duplication gauge will allow you to make your most complex cuts quickly and efficiently. The rods are thin and rigid with a cut line that is clear and easy to read. The teeth slide and lock to reproduce the contours as precisely as possible even if the shapes are very irregular. After that, all you have to do is take your measurements and draw them accurately. EASY: The tracing tool is very easy to use: to use it, you must first press the teeth of the gauge on the surface to be reproduced for perfect adjustment of the contour. Then, all you have to do is transfer the shapes obtained to the element to be cut and start cutting. Tracing and cutting will be child's play for you with this tool. MULTI-USE: You can use the duplication gauge for all your DIY work: cutting your pipes/door angles/frames/parquet floors/carpets/tiles/sheet metal/bodywork. It will become an indispensable partner in your work and will save you a lot of time.
