G321 Series wedge action grips are specially designed for use inside of environmental chambers. The grips are designed so the gripping portion is inside the chamber at operating temperature and the power cylinder (pneumatic or hydraulic) is outside, located in ambient temperatures. The grip heads are opened and closed remotely so they eliminate the need to cool them down before changing specimens. Sample changeover is quick. Because the grip head operates in the chamber, thermal gradients are minimized.

G321 Pneumatic wedge action grips feature grip bodies that move vertically to open and close the wedge jaws. As the bodies move, the jaws are held in position on the sample and open and close. The dual acting wedge jaws move simultaneously relative to the grip centerline, ensuring correct specimen alignment, removing bending strains that invalidate test results.

G321grips test round and flat samples and save time by offering quick and easy sample insertion. They feature constant clamp loading that protects samples from slipping as they stretch.

Note: Optional adapters or mechanical connections available for all test machines.
