The specimen is wrapped around a grooved 13mm diameter bollard and the free end is clamped tightly in place using a pair of friction washers and a thumbscrew. This minimises the chance of slippage within the grip, or of premature failure of the sample occurring due to stress concentrating at one point. The smooth groove accepts filaments up to 0.8mm diameter.
Fitted with a 10-32 UNF threaded swivel plate, which is designed to ensure specimen alignment when force is applied. 10-32 UNF threaded hole with grub-screw for connection to the base of a test stand or loadcell.
