V-jaw vice clamp, four jaws on screw-action adjuster, QC-20 fitting

Part: 432-678

432-678 is a vice fixture for mounting to the base of a test stand when performing tension and compression tests. It has four jaws, with two jaws being vertically spaced on either side. This provides increased stability by clamping at alternate heights on the sample container. Both sets of jaws are precisely adjusted equidistantly around the central axis by using a screw-action handle.
