Figure 2. Typical Wedge Grip (Rear)
The grips cover a wide range of common applications in materials testing. The two series
are similar, with the principal difference being that the series 2736 grips are rated for
high temperature use and configured with handles that facilitate their use in high-
temperature cabinets.
The grips are for static tensile testing only. The wedge action design lets the jaw faces
tighten onto a specimen without altering the vertical position of the faces in relation to
the specimen, letting you install a test specimen without exerting a tensile load on it
while tightening the grips. A compressive test load eliminates any gripping force and
causes the specimen to slip from the grips.
The open front design of the grip lets you change the jaw faces to accommodate flat,
round or different size specimens.
