Lufkin is a name you can trust. They know how to make an accurate pocket tape measure. An when it comes down to a detail, like putting a wider space between the zero mark and the next mark, they do it right. That extra space accounts for the thickness of the tape. The resolution is 100th of an inch diameter. It comes in a durable chrome-plated metal case. A company logo is imprinted on the front, and protected by a clear overlay. This is the best choice for a pipe diameter tape measure.
