Figure 3. Grips in the Closed and Open Positions
Closed
Adjust the specimen centering device before you place a test specimen between the
open jaw faces. When you turn the handles to close the grip on a specimen, the screw
action of the control nut and body threads move the body away from the test specimen
and push the bearing plate against the jaw faces. The position of the faces remain
vertically fixed, relative to the specimen, because the body is moving away from the
specimen. The anti-rotation pin prevents the grip from rotating as you tighten the control
nut.
