Starrett 657-2 Magnetic Base With Universal Indicator Holder

This versatile indicator holder has three pivots available for positioning the indicator where needed. All pivots are controlled by one tightening knob. It will hold with a 3/8" (9.5mm) stem (such as our No. 25 and Nos. 650 and 651 Series) indicator, any indicator with a standard dovetail mount (such as our Nos. 708, 709, and 811 Series), any indicator with a 1/4" (6.3mm) shank (such as our No. 196 Series). Any indicator with a 3/16" (4.7mm) shank (such as our Nos. 708, 709, 811 and 711 Series), any indicator with a body clamp (such as our No. 711 Series).
