Model# G109
Available Force Ratings Up to 500 kN (112,500 lbf)
Specimens Up to 50 mm (2 in) in diameter or thickness

Mechanical wedge grips feature easy specimen loading, self tightening and self alignment. Wedge gripping force increases as the pull load goes up - so these self-tightening grips are ideal when high clamp load is needed,such as gripping difficult hard materials. Tensile wedge jaws also offer a high mechanical advantage by the way they tighten. As the grip body is drawn up, inclined sides push against the matching side of the faces which move laterally against the specimen. The grip faces are spring loaded on the top, against the body. The open front allows faces to be interchanged as well as easy specimen loading.

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