VERSATILE: This handy contour gauge is used to measure and draw contours, firmly gauging shapes to be copied onto tiles or flooring panels for precise fitting around pipes, window sills, switches, sanitary fixtures, basins and architraves. EASY TO USE: To use, simply press the gauge against any object and then trace the contours of the surface. DURABLE: 260mm in length, the profile gauge has four magnets for attaching to metal surfaces and has metric and imperial measurements. It is made from durable, non-marking plastic.
