Spi 14-120-0 Telescoping Gage 1-1/4 to 2-1/8 in

Product Description

The SPI 14-120-0 is a telescoping gage used to measure internal diameters, bores, and slots across a range of 1-1/4 to 2-1/8 inches. The gaging spindles spring outward to contact the bore wall, then lock in place for transfer measurement with a micrometer or caliper. The overall length is 5-7/8 inches, and the handle measures 5 inches long. Constructed from hardened tool steel with a satin chrome finish, this gage is built for repeated use in shop and field environments. Machinists, toolmakers, and maintenance technicians use telescoping gages for bore inspection, engine work, and precision fitting tasks.

The SPI 14-120-0 suits applications in machine shops, maintenance facilities, and production environments where internal bore measurements are needed. Typical use cases include checking cylinder bores, bushing IDs, housing bores, and any internal diameter that falls within the 1-1/4 to 2-1/8 inch range. The compact overall length makes it practical for confined bore depths. It is used in conjunction with an outside micrometer to obtain a final measurement reading.

Key Features

• Measuring range of 1-1/4 to 2-1/8 inches for internal bore and slot measurement
• 5-7/8 inch overall length with a 5 inch handle for controlled feel and access
• Hardened tool steel construction for durability and wear resistance
• Satin chrome finish reduces glare and resists corrosion in shop environments
• Spring-loaded spindles lock in position for accurate transfer measurement

Compatibility

Designed for use as a transfer measurement gage for internal diameters in the 1-1/4 to 2-1/8 inch range; intended for use with an outside micrometer to obtain final dimension readings.

Installation Notes

Telescoping gages are hand-held measurement tools and require no installation. Insert the gage into the bore at a slight angle, allow the spindles to expand, then tighten the locking knob and withdraw the gage for transfer measurement. Use a calibrated outside micrometer across the locked spindle tips to read the bore diameter. Keep the gage clean and lightly oiled when stored to maintain finish and spindle function.
