Product Overview
JT Slocomb Company was a long-established American manufacturer known for producing durable, shop-grade measuring instruments. This larger-range outside micrometer was built for machinists and inspectors working beyond common 0-1 or 1-2 inch ranges. The digit counter design reflects an era focused on mechanical clarity, speed, and long service life rather than electronics.
