Adjustable Lock FunctionYou can adjust the tightness of the contour gauge according to your needs. The pencil can be moved up and down, making it easier to change the tip of the contour gauge. Contour gauges are particularly useful for contouring irregular and complex objects. It scribing tools can be locked and fixed after each adjustment to ensure measurement accuracy, which is convenient and quick.Contour Gauge Two Ends Can Be UsedPrecise contour gauge with lock has one pulley end and one pointer end. Precise contour gauge both ends can be used for shaping and measuring. The end of the pulley is smooth and wear-resistant, and the marking is smoother; the pointer end is more precise, suitable for high precision measurement. Contour copier can be replaced according to different contact scenarios.Precise measurement The precise contour gauge is easy to copy any shape, with our tool of precise contour gauge with lock, you can accurately measure, trace and copy all kinds of shapes (including irregular shapes) precise contour gauge accuracy up to 1mm for the best and most accurate data. You will never have to transfer profiles to paper or cardboard again.High Quality Material + Easy to CarryThe precise contour gauge with lock is made of high quality metal and ABS material, which is strong and durable, wear-resistant, rust-proof, just put the precise contour gauge in the toolbox and you can carry it with you, it contour gauge is powerful, easy to store and does not take up extra space .Precise Contour Gauge Wide ApplicationsPrecise contour gauge with lock is suitable for tracking skirting boards, countertops, front panels, tiling, laminate laying, carpet cutting, surface checking. sizing, molding and any work requiring reproduction of contours. Contour duplicator gauge our profile gauge tool will not scratch the original surface of the copied shape.
