Grips
Jaw Faces
Jaw faces are available for testing flat or round specimens. Use flat faces for flat
specimens and vee faces for round specimens.
Table 3 details the specific jaw face
specifications and specimen thicknesses. The specimen thicknesses shown in Table 3
apply to the 50 kN grips only when used with the spacers that are included with these
grips. Each catalog number provides 4 faces (2 for each grip).
The 2716-020 (50 kN) wedge action grips have a wider opening that enables you to test
a larger range of specimen thicknesses. These grips come with a spacer that must be
used when testing thinner specimens to ensure a tight grip. Refer to
Table 4 on
page 22 for additional information on specimen thicknesses for the 50 kN grips.
