ADMET rope and thread grips are designed for tensile testing of filaments, cords, yarns, fine wires, narrow ribbons, ropes, and other flexible specimens that can be difficult to secure with traditional grips. Their capstan-, drum-, or snubbing-style designs increase friction through controlled wrapping, allowing the specimen to be held securely without introducing damage or stress concentrations. Rope grips (GR-T) use opposing jaws with textured or serrated surfaces to maintain consistent grip strength and prevent slippage during testing. For more delicate materials, pneumatic thread-style grips (GT-T) guide the specimen around a smooth horn, distributing load evenly to protect the sample while maintaining reliable tensile loading. If you’re comparing grip styles or testing an unfamiliar material, our engineers can help you select the approach that best balances grip security and specimen protection.
