Spi 13-608-5 Indicator Positioner Holder 50 Lb Magnetic Base

Product Description

The SPI 13-608-5 is a magnetic-base indicator positioner holder designed to hold dial indicators, test indicators, and similar precision measurement instruments securely during layout, inspection, and machining operations. The unit features a post-style arm with ball and socket articulation, allowing the operator to position the indicator head at a wide range of angles and heights. A fine adjustment mechanism enables precise final positioning without disturbing the overall setup. The magnetic base provides 50 pounds of pull force, keeping the holder firmly anchored to ferrous machine surfaces, surface plates, and equipment frames throughout the measurement task.

This holder is suited for use in machine shops, toolrooms, quality control environments, and on production floors where dial or test indicators must be held in a repeatable, stable position. Typical applications include runout checks, surface flatness verification, part alignment, and fixture setup. The rectangular base and included post arm make it a general-purpose solution for a wide range of precision measurement workholding needs.

Key Features

• 50 lb magnetic pull force holds securely to ferrous surfaces and machine tables
• Post-style arm with ball and socket joint allows multi-angle indicator positioning
• Fine adjustment mechanism for precise final indicator placement
• Rectangular magnetic base included — no separate base purchase required
• Compact base footprint: 1.25 inches height, 1.25 inches length, 1.25 inches width
• 5 inch overall length accommodates a range of reach requirements

Compatibility

Designed as a general-purpose magnetic base indicator holder compatible with standard dial indicators and test indicators that mount via conventional dovetail, stem, or attachment clip connections. Suitable for use on any flat ferrous surface with sufficient pull area for the magnetic base.

Installation Notes

This holder is typically set up by machinists, tool and die makers, and quality technicians — no special licensing is required. Engage the magnetic base only after positioning the arm near the desired location to avoid abrupt movement of the indicator. Ensure the contact surface is clean and free of chips, oil film, or scale before activating the magnet, as surface contamination reduces effective pull force. Always verify the indicator is firmly clamped in the holder before taking measurements.
