Starrett 50192 Outside Caliper 36 Inch Leg Steel

Product Description

The STARRETT 50192 is a firm-joint outside caliper designed for taking outside measurements on workpieces in industrial, machining, and layout applications. Built with a 36-inch flat leg length and a polished steel construction, it handles large-scale measurement tasks up to 48 inches (1200mm). The screw-adjustment method combined with a quick-spring nut allows precise, repeatable leg positioning. This tool is typically used by machinists, millwrights, tool-and-die tradespeople, and precision layout technicians who need a reliable mechanical caliper for checking outside diameters, widths, and similar dimensions on large parts.

The 50192 is suited for shop floor and layout use where large outside measurements are required. Its firm joint maintains leg position during transfer, making it practical for comparing workpiece dimensions against a steel rule or surface plate. The 36-inch leg length targets applications involving large-diameter pipe, forgings, castings, structural stock, and similar oversized workpieces. It is compatible with Starrett 26 series components as noted by the manufacturer.

Installation Notes

This tool requires no installation in the traditional sense, but proper setup is important for accurate measurement. Before use, inspect the joint tension and leg alignment to confirm the firm joint holds position without drift. When storing, keep legs closed and protect the polished steel surfaces from moisture and impact to maintain measurement integrity. Calibration against a known reference dimension is recommended before use in critical applications.
