A profile gauge is a tool used to capture the shape of an object, allowing users to copy or recreate unique profiles. It consists of steel pins arranged on a single plane and can be used in various industries, such as construction, carpentry, and automotive. Different types of profiling tools allow users to capture different levels of detail.

A profile gauge is a tool used to capture the shape or contours of an object. These relatively simple tools allow users to copy or recreate unique profiles or designs that are difficult to duplicate. Workers and craftsmen in a wide variety of industries depend on this device during their manufacturing, processing and maintenance jobs. Profile gauge may also be referred to as a contour gauge in some parts of the world.

The standard profile gauge consists of dozens of steel pins arranged on a single plane side by side. The pins are connected along the center by a steel bar or metal strip. This center connector holds the pins together, but allows them to extend up or down until the tip of the pin touches the metal bar, but does not pass through.

When users rest this tool on the surface of an object, the pins slide out of any ridges or raised areas on the object. Once the gauge has captured this image, it can be carefully moved away from the object. The pins stay in place, positioned to replicate the profile of the item. Users can then hold this tool over a sheet of paper, wood or metal and trace the exact outline of the object to be duplicated. This tracing serves as a template, allowing the craftsmen to recreate the original object down to the last detail.

Different types of profiling tools allow users to capture different levels of detail in an object. Drives made with thin pins are designed for highly detailed work, such as capturing the profile of a specialty fastener. Models with thicker metal pins or strips can be used to duplicate larger objects, such as hand tools. Delicate items, such as wood or clay antiques, may require the use of a soft bamboo or plastic profile gauge. Large scale automotive applications generally require a very large profile gauge that uses flexible plastic strips to capture a pattern.

These tools are used in many production and industrial contexts. Builders rely on a profile gauge to copy the contours of architectural molding products. Carpenters can use this tool to recreate a unique table or chair leg. Artisans capture the outlines on clay pots, while makers use this tool to create custom or duplicate parts for a customer. A profile gauge also allows body technicians to replicate different body styles or parts.
