https://www.universalgripco.com/vise-gripsVise Grips. Vise Grips are the most basic type of grip used by a Universal Testing Machine (UTM) for tensile testing. There are two main types, Low-Profile and U-Style. The Low-Profile version is lower cost but has a limitation on the width of the grip face inserts. The U-style is more standard and can accommodate larger jaw inserts.
