These large circular bollard grips are designed for testing flexible wire-type materials with a maximum specimen thickness width of 2mm (0.08"). The sample is wrapped aroud the bollard and the free end is clamped tightly in place. This minimises the chnace of slippage within the grip or of premature failure of the sample occurring due to stress concentrating at one point.
