These precision tools can be used to elevate work above the surface of a plate to enable quick and easy inspection of piece parts with shoulders or steps, in addition to many other uses. Our parallels are provided in matched pairs with either two or four finished faces. Two-face parallels have two narrow faces finished flat and parallel. Four-face parallels have wide faces finished flat and parallel, as well as the two narrow faces. Parallels are available in laboratory grade AA (.000025” per 6”) or inspection grade A (.000050” per 6”).
