Robert Larson 850-1215 Outside Caliper 150mm

Product Description

The ROBERT LARSON 850-1215 is a 150mm outside caliper designed for precise measurement and layout work in trade and workshop settings. Built with polished steel construction and brass fittings, this caliper delivers reliable dimensional readings on round stock, pipe, fittings, and other external surfaces. A quick-nut adjustment mechanism allows fast, accurate positioning without losing your setting mid-measurement. At 0.305 pounds, it is lightweight enough for continuous hand use. Plumbers, pipefitters, machinists, and general tradespeople reaching for a dependable analog measuring tool will find this caliper straightforward to use and easy to maintain.

The 850-1215 suits applications where quick outside diameter verification is needed on the bench or in the field. Typical uses include checking pipe OD before fitting selection, verifying stock dimensions during fabrication, and confirming tolerances during layout work. Its analog bow-leg design requires no battery and functions reliably in dirty or wet shop environments where digital calipers can be problematic.

Key Features

• 150mm measuring range for outside dimensions
• Quick-nut adjustment for fast, repeatable positioning
• Polished finish with brass fittings for durability and corrosion resistance
• Lightweight at 0.305 pounds for extended hand use
• Analog bow-leg design requires no power source

Compatibility

Designed as a general-purpose outside caliper suitable for trade, fabrication, and layout applications requiring external measurement up to 150mm.

Installation Notes

No installation required. This is a handheld measuring instrument. Before use, verify the caliper closes fully to zero with legs in contact to confirm no damage occurred in transit. Store in a dry location to protect the brass fittings and polished finish from corrosion. Do not use as a pry tool or apply lateral force to the legs, as this will affect calibration.
