Yarn, Rope, Wire & Cord Grips

These grips are specifically designed for testing thin, flexible materials. They ensure a secure hold to maximize test result accuracy and repeatability.

Often referred to as Bollard grips, these are specialized grips available in configurations to secure both flat and round samples. For filament material such as string, yarn, threads and suture material, the sample is looped around the bollard and then secured with a vise-type clamp. The larger the bollard the better it helps to distribute the stress on the specimen more uniformly and reduce premature sample rupture.

For thick material with high tensile values, very larger bollards or drums are used where the sample will be wrapped around it multiple times. This provides a greater contact and frictional area that allows the stress to be distributed over a larger section of the sample and reduces premature failure or sample slippage.
