Contour or Profile Gauges are indispensable when you need to copy an existing profile or molding. Profile gauges consist of a set of small diameter stainless steel pins that are held tightly against each other in a steel frame but can still move independently and hold their position. When pressed against a profile the gauge conforms to the profile creating a perfect negative profile and a corresponding positive profile on the other side. These profiles can now be used to draw the contour or duplicate it on to another surface. These gauges have either .8mm (150 mm gauge) or 1 mm (200 and 300 mm gauges) diameter stainless steel pins which produce much smoother curves and finer details than plastic gauges. Maximum profile depth is 2 inches for the 150mm, 3-1/8 inches for the 200mm and 5-1/8 inches for the 300mm. Made in Japan, Manufacturer: Shinwa
