Spi 54-253-0 Comparator Gage Stand Granite Rectangular Base

Product Description

The SPI 54-253-0 is a granite comparator gage stand designed for precision measurement setups in machine shops, quality control labs, and inspection stations. The stand features an articulated arm style and a solid granite rectangular base that provides stability and vibration damping during dial indicator work. The base measures 12 inches in length, 8 inches in width, and 2 inches in height. The post rises 10 inches, with an overall assembled height of 12 inches. An indicator holder is included. This stand is installed and used by machinists, metrology technicians, and quality control inspectors who require a stable, repeatable surface for comparative measurement tasks.

This comparator gage stand is suited for use on surface plates, benches, and inspection tables in both production and laboratory environments. It is appropriate for residential machine shop work or commercial quality assurance operations where surface measurement accuracy is required. The granite base resists corrosion and temperature-related dimensional changes better than cast iron alternatives, making it a reliable choice for controlled inspection environments. No fine adjustment mechanism is included, and the stand does not come with a dial indicator or anvil.

Key Features

• Granite rectangular base for vibration damping and dimensional stability
• Articulated arm style allows flexible indicator positioning
• Overall height of 12 inches with a 10-inch post height
• Large base footprint: 12 inches long by 8 inches wide by 2 inches high
• Indicator holder included — dial indicator sold separately

Compatibility

Designed as an OEM-style replacement or direct-use comparator gage stand compatible with standard dial indicators and indicator holders used in precision metrology setups.

Installation Notes

This stand is set up by machinists or metrology technicians on a flat, clean surface plate or inspection bench. Ensure the surface plate or bench is level before positioning the stand. Secure the indicator holder firmly before taking measurements to prevent indicator drift. No electrical power or special tooling is required for setup.
