Designed to suit the ElectroPuls^® test instruments, the 2742-102 mechanical wedge action grips are suitable for tension, compression and reverse-stress testing on a wide range of specimens and materials. The grips are mechanically operated and the open-fronted design provides easy specimen insertion, positioning and clamping.

Principle of OperationThe wedge action principle of the grips allows them to be tightened easily, by hand (or spanner for additional gripping force), onto the specimen without altering the vertical position of the faces in relation to the specimen. This Instron^® design of a moving grip body, not jaw face, makes it possible to pre-select the exact point at which the specimen is gripped, with a consistent gauge length and with no compressive force being applied, which may cause specimen buckling.

The open front design allows for quick and easy changing of the jaw faces. The jaw faces are serrated for optimum gripping performance and the serrations are designed to minimize damage to the specimen surface.

Attachment kits to suit ElectroPuls instruments and other systems are available.
