Spi 20-314-1 Magnetic Indicator Base 2.874 X 1.969 X 2.165 in

Product Description

The SPI 20-314-1 is a magnetic indicator base designed to hold dial indicators, test indicators, and similar precision measuring instruments during inspection and layout work. The base uses a strong permanent magnet to mount securely to ferrous machine surfaces, allowing technicians and machinists to position an indicator arm exactly where needed. The magnetic pull is rated at 100 kilograms, providing a stable hold on mills, lathes, surface plates, and other iron or steel workholding surfaces. At 2 pounds, the base is compact enough for bench or field use without adding excessive mass to the setup.

This indicator base is suited for machine shops, tool rooms, and maintenance environments where precise measurement of runout, surface variation, and part alignment is required. It is typically used by machinists, toolmakers, metrology technicians, and maintenance mechanics performing equipment alignment or quality inspection tasks. The base footprint of 2.874 inches in length by 1.969 inches in width keeps it manageable on crowded setups.

Key Features

• 100 kg magnetic pull for secure mounting on ferrous surfaces
• Compact base footprint: 2.874 inches long by 1.969 inches wide
• 2.165 inch base height accommodates standard indicator arm assemblies
• 2 pound total weight supports portable use on machines and surface plates
• Magnetic design eliminates the need for clamps or secondary mounting hardware

Compatibility

Designed as a general-purpose magnetic indicator base compatible with standard dial indicator and test indicator setups used on ferrous machine tool surfaces.

Installation Notes

Place the base on a clean, flat ferrous surface and engage the magnet before attaching the indicator arm. Ensure the surface is free of chips, coolant, or debris that could reduce magnetic contact and holding force. Indicator arms and rods should be secured firmly before taking measurements to prevent drift. No electrical power or special tooling is required for mounting or removal.
