Spi MS160412019 Indicator Positioner Holder 176 Lb Pull

Product Description

The SPI MS160412019 is an indicator positioner holder designed to secure dial indicators, test indicators, and similar gauging instruments during precision measurement tasks. The unit features an articulated arm with fine adjustment capability, allowing technicians to position an indicator with repeatable accuracy. A rectangular magnetic base provides 176 pounds of pull force to hold the assembly firmly to ferrous surfaces. At 310 mm in overall length, the arm offers adequate reach for most bench and machine-tool setups. This holder is used by machinists, metrology technicians, and quality control personnel in manufacturing and inspection environments.

The MS160412019 is suited for use on surface plates, machine tool beds, milling tables, lathes, and other ferrous workholding surfaces where a stable, adjustable indicator mount is required. The fine adjustment feature allows precise repositioning of the indicator tip without disturbing the magnetic base. The articulated arm configuration provides flexibility in reach and angle, making it practical for both in-process machining checks and dedicated inspection setups.

Key Features

• 176 lb magnetic pull force for secure hold on ferrous surfaces
• Articulated arm style allows flexible positioning and reach adjustment
• Fine adjustment mechanism enables precise indicator tip placement
• Rectangular base with 35 mm height and 35 mm length footprint
• 310 mm overall arm length for extended reach applications

Compatibility

Designed as a general-purpose indicator positioner holder compatible with standard dial indicators and test indicators used in precision measurement and inspection applications on ferrous surfaces.

Installation Notes

Engage the magnetic base only on clean, flat ferrous surfaces free of chips, coolant, and debris to achieve rated pull force. Before positioning the indicator, ensure the articulated arm joints are loosened sufficiently to allow adjustment without forcing the linkage. Lock all arm joints securely before taking measurements to prevent drift. Disengage the magnetic base before moving the holder to a new location to avoid dragging across precision surfaces.
