Spi 13-607-7 Indicator Positioner Holder 50 Lb Magnetic

Product Description

The SPI 13-607-7 is a magnetic-base indicator positioner holder designed to secure dial indicators and similar precision measurement instruments during inspection, layout, and machining operations. The unit features a 50-pound magnetic pull force, a post-and-clamp arm style, and a fine adjustment mechanism that allows precise positioning of the indicator tip. The round magnetic base provides stable, vibration-resistant mounting on ferrous surfaces such as machine tables, surface plates, and lathe beds. At 7 inches overall length, it gives machinists and quality technicians the reach needed for most standard setups.

This indicator holder is suited for use in machine shops, toolrooms, and quality control environments. It is commonly used when tramming a mill head, checking runout on a lathe, or performing surface plate inspection work. The included magnetic base with arm eliminates the need for a separate stand, making it a compact, self-contained setup tool. Fine adjustment capability reduces the time needed to zero an indicator without repositioning the entire base.

Key Features

• 7 inch overall length provides adequate reach for most setups
• Base measures 1.25 inches in height, 1.25 inches in length, and 1.25 inches in width

Compatibility

Designed for use with standard dial indicators and test indicators in machining and inspection applications that require magnetic-base mounting on ferrous work surfaces.

Installation Notes

Machinists and metrology technicians typically install this holder on any clean, flat ferrous surface. Ensure the mounting surface is free of chips, coolant, and debris before engaging the magnetic base to achieve full pull force. Power down or lock out any rotating equipment before positioning the indicator arm near a spindle or rotating part. Periodically inspect the clamp and arm joints for wear or looseness that could affect measurement accuracy.
