Spi 14-400-6 Indicator Positioner Holder 175 Lb Magnetic

Product Description

The SPI 14-400-6 is a magnetic-base indicator positioner holder designed to secure dial indicators, test indicators, and similar precision measuring instruments during inspection and machining operations. It features a 175 lb magnetic pull force delivered through a flat rectangular base, giving machinists and quality control technicians a stable, vibration-resistant mounting platform on any ferrous surface. The arm assembly uses a post and rod configuration that allows the indicator to be positioned at a wide range of heights and angles. Overall length reaches 9 inches, providing sufficient reach for most workholding setups on mill tables, surface plates, and lathe beds.

This holder is suited for use in machine shops, tool rooms, and quality assurance environments where a dial or test indicator must be held rigidly in place during measurement runs. The magnetic base activates and deactivates without tools, making it practical for frequent repositioning between setups. It is typically used by machinists, toolmakers, and metrology technicians working with vertical and horizontal spindle machines or surface plates.

Key Features

• 175 lb magnetic pull force for secure hold on ferrous surfaces
• Post and rod arm style allows flexible indicator positioning
• Flat rectangular base sits flush on machine tables and surface plates
• 9 inch overall length provides extended reach for varied setups
• Includes holder and magnetic base with arm as a complete assembly
• No fine adjustment mechanism — straightforward, robust construction

Compatibility

Designed as an OEM-style replacement and standard-fitment magnetic base holder compatible with most dial indicators and test indicators using conventional dovetail or post-mount attachment styles.

Installation Notes

A licensed machinist or metrology technician should verify that the mounting surface is clean, flat, and free of chips or coolant before activating the magnetic base. Deactivate the magnet fully before repositioning to avoid sudden indicator movement that could damage the instrument. Always confirm the arm and rod clamp screws are fully tightened before taking measurements. No electrical power or specialty tools are required for setup.
