The Widen contour gauge is a tool used for accurately measuring and replicating the shape of irregular objects, such as curved tile edges, laminate flooring, moldings, and pipes, to name a few. It consists of a series of thin, movable pins that are attached to a frame. Here's how it works:

1. Usage: To use the Widen contour gauge, you simply press it against the object you want to measure. The pins will conform to the object's shape, creating an impression of its contours.

2. Locking Mechanism: Once you have obtained the contour of the object, you can lock the pins in place using a locking mechanism on the gauge. This allows you to transfer the shape to another material or surface accurately.

3. Transferring Measurements: To transfer the shape, you can either trace the contour onto the material directly or use the gauge itself as a guide for cutting or shaping the material to match the original object's contours.

4. Accuracy: The Widen contour gauge is known for its accuracy in capturing intricate shapes and contours, making it a valuable tool for various applications in construction, woodworking, and crafts.

5. Variants: There are different variants of contour gauges available, including wider ones like the Widen contour gauge, which allows for measuring larger and more complex shapes with greater precision.

In summary, the Widen contour gauge is a useful tool for accurately measuring and replicating the shape of irregular objects, making it an essential tool for professionals and DIY enthusiasts alike.
