For certain applications, like turning the crank under test with the gage in place, the Starrett 696B balancing attachment can be adjusted to maintain the face of the indicator upward or in desired position. To install on a strain gage in use, remove the knurled clamping nut, then the doweled plate or end strap at either end by the screw.

The unit is then positioned over the hubs on two sides of the indicator head. A spring plunger provides the friction that holds the balance in proper relation to position. The parts are nickel-plated. For use with Starrett 696, 696M Crankshaft Distortion Dial/Strain Gage.
