A contour gauge is a shape-copying ruler designed for precise measurements of irregular surfaces. It uses a row of fine stainless steel pins that slide smoothly and lock in place to capture curves, arcs, corners and complex profiles exactly as they are.
Use it to measure around door frames, window frames, pipes, molds, automotive parts and artistic templates. Once the pins conform to your target shape, the locking mechanism—either a lever or screw—holds them firmly in position. This prevents any movement or distortion while you transfer the profile to your workpiece, ensuring a perfect fit.
The 10 inch size suits most household and light workshop tasks. The stainless steel construction resists corrosion and wear. Simply position the gauge against your shape, allow the pins to settle, engage the lock, then use the captured profile as a template for cutting, fitting or replication.
