Telescoping Gages are used as indirect measuring devices for the inner diameters of pipe, holes and slots, which can then be transferred to a micrometer for pinpoint accuracy. General's Telescoping Gage Set provides you with six precision gages, capable of measuring widths and diameters from 5/16"" all the way to 6"". The extended-length shafts are great for reaching down into the hole, such as for measuring the diameter of a pipe below a reducing coupling or flare. This set is packaged in a vinyl case for storage.
