For more versatility than other low-profile holders, this holder has six locations for mounting indicators and accessories, including two mounting holes and four places to mount an indicator lug back with the included thumb screws.

Use a swivel clamp to attach an indicator to the positioning arm.

The base is comprised of adjustable magnetic pins which allow it to conform to any shape and grip most metal surfaces.

Mount these holders into a machine spindle and use with your indicator to center workpieces.

A heavy cast iron base adds stability. These stands hold indicators in place for taking accurate readings.

These holders come with a calibration certificate traceable to NIST states that the granite base has passed a test for surface accuracy. The extremely tight flatness tolerances of the granite allow for nearly frictionless workpiece movement and provide an accurate reference plane for inspection work.

Attach the C-clamp on this holder to your Bridgeport J head to take indicator measurements without obstructing the cutting tool.

Position the arm by adjusting joints at the top, middle, and bottom.

Use with swivel clamps to position indicators.
