Manual Non-Shift Wedge Grips
Manual non-shift wedge grips are versatile grips for tensile testing a wide variety of materials, including metals, plastics, and composites. The open-front design allows easy insertion of specimens and exchange of grip faces. The self-tightening action means samples are held firmly within the grip faces, minimizing slippage during testing.
Each manual non-shift wedge grip set includes upper and lower grips and file-teeth grip faces for flat plate specimens. Standard grip sets are available with maximum capacity between 5 kN (1,100 lbf) and 300 kN (66,000 lbf). In addition, grip sets are available with wide 50 mm (2.0 in) file-teeth grip faces for grips with maximum capacity between 5 kN and 100 kN (22,000 lbf). Grip sets of 250 kN (55,000 lbf) and 300 kN are supplied with 50 mm file-teeth grip faces as standard.
A comprehensive selection of additional grip faces can be found in the document on Grip Faces for Manual and Pneumatic Non-Shift Wedge Grips. Options include grip faces especially designed for rods, wires, materials with high hardness, and composite materials.

Operation
The wedge shape design of the manual non-shift wedge grip enables vertical movement of the grip frame while grip faces stay in the same position, simplifying specimen positioning. Movement of the handle to tighten the grip simultaneously pushes both grip faces together horizontally, by action of the wedge-shaped grip body, applying a strong clamping force and minimizing the generation of vertical test forces. During testing, increased tension wedges the grip faces tighter against the frame, increasing the gripping force applied to the specimen.
Grip faces stay in the same vertical position when opening and closing
