Contour Gauge Duplicator is designed to copy or record the exact shape of irregular shapes when you install carpet or tile in an area surrounded by stairs, furniture, and plumbing materials. Recording the exact shape helps the floor designers make a perfect cut, leading to finished and precise work. It comes with a double scale copier i.e. inch and centimeter to provide accuracy in measurement. As compared to regular contour gauges it is 5.9 inches wider, which helps to replicate bigger areas.
