Adjustable locking functionThe tightness of the contour gauge can be adjusted as needed. The pencil can be moved up and down making it easy to change the end of the profile gauge. Edge gauges are particularly suitable for cutting irregular and complex objects. The tracking tool can be locked and fixed after each adjustment, ensuring accurate and convenient measurements. Contour Gauge Can Be Used at Both Ends Precision contour gauge with lock has a pulley end and a pointer end. Precise profile gauge ends are available for forming 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, and the contour copier can be replaced according to different contact scenarios. Precision measurementPrecision contour gauge easy to reproduce any shape, with our precision locking contour gauge tool you can accurately measure, trace and reproduce various shapes (including irregular shapes) with precise contours up to 1mm accuracy. p> Premium Material + Easy CarryingThe precision profiler with lock is made of high quality metal and ABS, durable, wear-resistant, rust-proof, just put it in the tool box and use it. Widely Used Precision ProfilerThe locking precision profiler is suitable for tracking baseboards, countertops, front panels, tiles, laying laminates, carpet cutting, dimensional control, molding and any work requiring the reproduction of profiles. Contour Replicator Measure Our Contour Replicator tool will not scratch the original surface of the copied shape.
