Wedge grips - consisting of 2 interchangeable or fixed jaws in the shape of a wedge which are secured in a metal body.
Designed such that, when under tension, the two jaw faces are drawn tighter together in a firmer hold upon the specimen. For specimen removal /insertion the wedge-jaws are quickly and easily opened/closed by using a lever to move them up and down within the body. The initial clamping force to hold the specimen before the test begins is achieved by tension springs acting to bring the wedge-jaws together.
An ideal ‘general-purpose’ grip for testing plastic and metal dumbbells, sheets, strips and other flat or round specimens.
