Spi MS180905012 Magnetic Indicator Base

Product Description

The SPI MS180905012 is a magnetic indicator base designed to hold dial indicators, test indicators, and similar precision measuring instruments securely during inspection and layout work. The base uses a magnetic mounting system with 80 kilograms of magnetic pull force, locking firmly to ferrous machine surfaces, surface plates, and workpiece fixtures without clamps or fasteners. The adjustable post and rod assembly allows the instrument to be positioned at the angle and height needed for the measurement task. Installed by machinists, tool-and-die technicians, and quality control personnel, this base is standard equipment in machine shops and fabrication environments where repeatable indicator positioning is required.

The MS180905012 is suited for use on manual mills, lathes, surface grinders, inspection tables, and similar ferrous metal surfaces. The base measures 2.36 inches in length, 1.97 inches in width, and 2.17 inches in height. The rod extends 6.50 inches to provide reach for positioning the indicator over a workpiece. It is appropriate for both shop-floor dimensional verification and precision setup work in production and toolroom settings.

Key Features

• 80 kg magnetic pull force for firm, shake-resistant mounting on ferrous surfaces
• Base length of 2.36 inches, base width of 1.97 inches, base height of 2.17 inches
• Rod length of 6.50 inches for flexible indicator positioning
• No clamps or fasteners required for mounting
• Compatible with standard dial and test indicator mounting stems

Compatibility

Designed as a general-purpose magnetic indicator base compatible with dial indicators and test indicators that use standard mounting post and clamp configurations on ferrous metal surfaces.

Installation Notes

Place the base on a clean, flat ferrous surface and engage the magnetic lock before attaching the indicator. Ensure the surface is free of chips, coolant film, or debris that could reduce magnetic holding force. Deactivate the magnet before repositioning to avoid dragging the base across precision surfaces. No special tools are required for setup, but indicator mounting clamps should be tightened securely before taking measurements.
