Deep Throat Thickness Gages are precision measuring tools used to measure the thickness of materials in hard-to-reach or confined areas. They are designed with an extended reach or "throat" that allows them to measure the thickness of materials in areas where traditional thickness gages cannot reach.

Deep Throat Thickness Gages are commonly used in a variety of applications, such as quality control in manufacturing, inspection of automotive and aerospace parts, and measuring the thickness of pipes or vessels in the oil and gas industry. They are available in a range of sizes and with various features, such as digital displays or interchangeable jaws, to suit different measurement needs.
