Snubbing Grips for Wire and Cable Tensile Testing

Description

Snubbing grips, also known as capstan grips, are used for tensile testing of wires, ropes, fiber bundles, and electrical cables that tend to slip during loading. The specimen is wrapped around a curved mandrel or capstan to create friction along its length. This distributes the load and avoids concentrating stress at a single point.

This setup makes it possible to accurately measure the tensile strength of materials like steel cables, braided conductors, and reinforced wire products. The free end of the specimen is commonly secured with a clamp or wedge insert to maintain stable loading throughout the test.

Snubbing grips are used in cable manufacturing, laboratory testing, and quality control for structural and infrastructure applications. They are selected for specimens that require secure holding without surface damage and are suitable for testing procedures performed under ASTM, ISO, and related standards.
