MECHANICAL WEDGE ACTION T-GRIPS (LEVER-OPERATED)
These economical and versatile assemblies are designed for simplified specimen insertion and removal, a feature that saves time and reduces operator fatigue. An assortment of interchangeable jaws will fit in the T-grip holders, which allows for acceptance of a range of sizes in both flat and round specimens. To increase ease of operation, the locking mechanism of the lower holder keeps the grip jaws open so that one-handed specimen insertion is possible.
2.9
The upper and lower grip bodies are structurally the same. Each grip body has a pocket that holds a pair of grip jaws and utilizes a wedge design. This wedge design causes the grips to further tighten as load on the specimen is applied, reducing slippage.

General Purpose Static Tensile Grips
Principle of Operation
All capacities of T-grips are offered with lever/spring actuation, which uses a lever to raise and lower the jaws in the grip pocket, and a spring to provide the initial clamping force on the specimen. When loading a specimen, the operator locks the bottom jaw open, then opens the upper jaw and places the top half of the specimen inside. Once the specimen is clamped securely within the upper jaw, the operator positions the bottom half of the specimen into the lower grip jaws and unlocks the jaws, providing clamping force and securing the specimen so that the test may be conducted.
Application Range • Type of loading: Static tension • Specimen material: Wires, plastics, metals, elastomers • Specimen types: Flat or round specimens
