Starrett 436.1XRL-3 2-3in 0.001in Ratchet Stop Outside Micrometer

The Starrett No. 436.1XRL-3 is a new mechanical outside micrometer with a 2–3 inch measuring range and 0.001 inch graduation, readable to 0.0001 inch accuracy via the vernier scale on the sleeve. The frame is a large, heat-treated, black-enamel cast iron C-frame with an integral insulating thermal guard to minimize measurement error from hand heat transfer; the anvil and spindle faces are hardened and ground carbide-tipped for wear resistance. The thimble incorporates a ratchet stop (indicated by the "RL" suffix) that applies consistent, repeatable measuring pressure regardless of operator technique, and the "XRL" designation confirms the extra-large frame size accommodating the 2–3 in range. Graduated in 0.001 in increments on the sleeve with a 25-division vernier scale for 0.0001 in resolution, this micrometer is suited for precision OD measurement in toolrooms, quality inspection, and general machining environments.
