Spi CMS160409003 Indicator Positioner Holder 66 Lb

Product Description

The SPI CMS160409003 is a magnetic-base indicator positioner holder designed to secure dial indicators and test indicators during precision measurement work. It features an articulated arm with a 3/8-inch clamping diameter, allowing the indicator to be positioned and held at a wide range of angles. The magnetic base delivers 66 pounds of pull force, keeping the holder firmly anchored to ferrous machine surfaces during setup, inspection, and quality control operations. The rectangular base includes mounting geometry suited to standard surface plates and machine tool tables. Machinists, tool-and-die technicians, and metrology professionals are the primary users of this type of holder.

This holder is used in machine shop environments, toolroom settings, and on production floors where dial indicators or test indicators must be held in a fixed position relative to a workpiece or fixture. The articulated arm design allows fine positional adjustment without moving the base. The 66-pound magnetic pull provides stable holding on lathes, milling machine tables, surface plates, and similar ferrous work surfaces. It is not suited for non-ferrous or non-magnetic surfaces without a supplemental mounting adapter.

Key Features

• 66-pound magnetic pull force for secure anchoring on ferrous surfaces
• Articulated arm allows multi-axis positioning of the indicator
• 3/8-inch (9.53 mm) clamping diameter accepts standard indicator stems
• Rectangular magnetic base included
• Overall length of 7.88 inches for extended reach
• Base height of 1.38 inches for low-profile setup clearance

Compatibility

Designed as an OEM-style magnetic indicator holder compatible with standard 3/8-inch stem dial indicators and test indicators used in general metrology and machine shop applications.

Installation Notes

Installation requires a clean, flat ferrous surface free of chips, coolant, and debris to achieve full magnetic pull contact. Engage the magnetic base switch fully before releasing the arm to prevent the holder from shifting. Confirm the articulated arm lock is tightened at each joint before taking readings. Do not use on non-magnetic surfaces such as aluminum, granite surface plates, or stainless steel without an appropriate supplemental clamping fixture.
