General Purpose, self tightening grips feature an eccentric roller design ideal for dumbbell and flat specimens. The roller operates using a basic cam jamming principle. The rollers have a cross hatched, serrated finish that help prevent slipping. Clamps hold the sample securely against the horizontally grooved back panel. Maximum sample width is 25mm (1.0 in). Maximum sample thickness is 5mm (0.2 in).
Applications: Ideal for tensile testing of sheet materials including polymers and rubbers
