Starrett 1911 Slide Rail Micrometer

For match level accuracy, slide-to-frame fit on 1911-style au- tos must be closer than a gnat’s whisker. This specially modified Starrett mike precisely measures the thickness of the slide’s "rails". Makes choosing the correct slide fitting bar quick and accurate. No guesswork. Take measurement at three points along the slide, average readings together, and select a slide fitting bar (listed elsewhere) .001" to .002" thicker. Mfg: Starrett SPECS: Stainless steel, 2- 1/2" (6.3cm) overall. Carbide measuring faces read .0000 to .4265" (10.8mm). Includes plastic case.
